摘要： PROBLEM TO BE SOLVED: To reduce shadowing by correcting the increase of an effective voltage due to a crosstalk noise generated in a non-selective voltage of a common driver by the output change of a segment driver. SOLUTION: The voltage waveform of a common electrode is discribed by a dot line in SEG1, SEG2. In order to prevent the generation of difference in an effective voltage by causing a crosstalk noise in the common electrode, correcting signals CC1, CC2 are formed from the crosstalk noise and the output waveform of SEG2 is corrected (d). At this time, at the changing point of the output signal of a segment driver at the time of white background display of the segment driver, the rise noise of the output signal of segment driver shown by SEG1 and the fall noise of the output signal of segment driver shown by SEG2 are detected by a circuit for detecting a crosstalk noise propagating to the common driver side as the crosstalk noise amount generated on a non- selected level VM, respectively, and outputted to the driver as CC1, CC2 pulse signals.

摘要： PROBLEM TO BE SOLVED: To reduce the number of parts in a conversion circuit and to reduce a propagation delay by respectively providing specified an inducement means and a reference potential setting means. SOLUTION: A capacitor (inducement means) 202 and a diode (reference potential setting means) 203 are used for the conversion circuit 108, and the input terminal and the output terminal of the conversion circuit 108 are insulated by the capacitor 202, and the diode 203 is connected between the output terminal and a minimum voltage V5 of a ternary scan line driver so as to become an inverse bias. Thus, since the minimum voltage of the inversion voltage of the output terminal side induced by a voltage value applied to the input terminal moves (level shift) to V5 to V5+5V being the input voltage range of the ternary scan line driver 106, the conversion circuit 108 with the number of less parts and the reduced propagation delay is constituted, and a drive circuit substrate loading a drive circuit is miniaturized.

摘要： PURPOSE: To provide a reflection type liquid crystal display device in which misalignment of display colors is prevented and a bright display is obtd. in a bright state. CONSTITUTION: The reflection type liquid crystal display device consists of a first substrate 1 and a second substrate 2 facing each other to hold a liquid crystal layer 8 in between. A first transparent electrode 4 and a first oriented film 6 are formed don the liquid crystal layer side of the first substrate 1. A color filter layer 9 covered with a flattening layer 10, second transparent electrode 5, and second oriented film 7 are successively formed on the liquid crystal layer side of the second substrate 2. A polarizing plate 3 is disposed on the incident light side (outer surface) of the first substrate 1, and a reflecting plate 11 is disposed between the second substrate 2 and the color filter layer 9 covered with the flattening layer 10. By this method, the transmission optical length of the incident light and reflected light can be decreased and the distance Δd' between the incident position of the incident light and the outgoing position of the reflected light is reduced so that the incident light and reflected light can transmit through a same pixel and a same color filter layer 10.

摘要： PURPOSE:To inhibit the attenuation in signal transfer for an amplifier circuit incorporated in a device by forming an extremely larger parasitic capacitance in an input side of a second capacitor compared with a parasitic capacitance on the output side. CONSTITUTION:A first conductive layer 71 is formed on an insulation film 70 on the main surface of a semiconductor board. Then, a second conductive layer 73 is formed by way of an insulation film 72. By way of an insulation film 74 there is further formed a third conductive layer 75. Furthermore, an aluminum wiring layer 77 is formed by way of an insulation film 76 and connected to the third conductive layer 75. An aluminum wiring layer 79 is further formed by way of the insulation film 76 and connected to the second conductive layer 73. A capacitor under this construction uses the wiring layer 77 as its input and the aluminum wiring layer 79 as its output. A large capacitance with the board is provided on the input side in this case. This construction makes it possible to inhibit the attenuation in signal transfer for an amplifier circuit incorporated in the device.

摘要： PURPOSE: To simplify a scanning electrode driving means by providing specific voltage generating means, voltage switching means and signal voltage conversion means, respectively. CONSTITUTION: The voltage generating means 11 forms two kinds of operating voltages i.e., first and second voltage sources in accordance with a positive driving voltage and a negative driving voltage in the scanning electrode driving means 103. The voltage switching means 12 supplies by switching the first or second voltage source corresponding to an AC forming signal 4. The scanning electrode driving means 103 is operated setting the first or second voltage source supplied from the voltage switching means 12 as the operating voltage. The signal voltage conversion means 13 receives the output voltage of the voltage switching means 12, and converts a row clock signal 106 supplied from the outside to the row clock signal of level corresponding to the output voltage, and supplies it to the scanning electrode driving means 103. In this way, since only the operating voltage corresponding to the positive and negative driving voltages is applied to the scanning electrode driving means 103, its breakdown strength can be saved to the half of the amplitude of an actual driving voltage applied to a scanning electrode.
