摘要： A liquid crystal panel used for a flat display can be produced at a high yield while scattering of hue and optical interference are vanished to realize a high quality display.
At each interface between adjacent layers (for example between a top substrate (1) and a color filter (8), or between a color filter (8) and an ITO film (4), or the like) the difference of the index of refraction is set to be 0.2 or less.
To that purpose an intermediate layer (12,13) may be inserted between two adiacent layers where the difference of the index of refraction is larger than 0.2.
Alternatively, if a layer has a difference of index of refraction larger than 0.2 with respect to an adjacent layer at either side thereof then its optical path "nd" is chosen to satisfy the relation

n d = N λ 2

where λ denotes a design wavelength, and N a positive integer.
Preferentially λ = 550 nm (green color wavelength).
Still alternatively, a minute rough surface of 0.01-0.5 µm may be formed at any interface where the difference of the index of refraction is larger than 0.2.

摘要： A video projector utilizes a reflective liquid crystal light valve of the active matrix system and a polarizing beam splitter. An active matrix array circuit of the light valve has pixel electrodes arranged in a matrix mattern. The pixel electrodes each has a reflective surface for reflecting a light beam and protects corresponding switch elements from the light beam. There are provided at least two switch elements for each of the pixel electrodes so as to enhance the redundancy of the array circuit. Further, each pixel electrode is provided with a suitable additional capacitance.

摘要： A liquid crystal display unit including a plurality of subpixels (21a, 21b) in each pixel (21) provides superior gradation over a wide viewing angle, and is produced with no increase in manufacturing cost and no deterioration of desired properties (such as reduction in brightness, contrast and response). No additional manufacturing step is required since a control capacitor electrode (8c) is formed at the same time as source and drain electrodes (8a, 8b) constituting a thin-film transistor (24). By controlling the ratio of display area and the difference in applied voltage of the subpixels (21a, 21b), preferable viewing angle properties are obtained. The display properties at the boundary of subpixels are improved by controlling the gap width and the direction of boundary of the subpixels (25), thus providing a bright display.

摘要： Pixel electrodes in the periphery of a thin film transistor array (peripheral part of the display screen) of an active matrix type liquid crystal display device are directly electrically shortcircuited with signal lines (3), whereby an alternating current signal is always applied to the pixel electrodes without being passed through a thin film transistor (1) as a switching element. Thereby the liquid crystal arranged on the peripheral part of the display screen is driven in a static state resulting in a high stability against the display characteristics.

摘要： An improved arrangement of a liquid crystal display device is provided in which the redundancy of known but unwanted TFT (thin film transistor) defect is suppressed so that the yield per finished liquid crystal display device products can be increased without declination in the picture quality. Each pixel of the liquid crystal display device arranged at an intersection of one of scanning lines and one of signal lines is provided with two or three TFTs and also, a storage capacitor which is formed of a portion of a gate insulating layer sandwiched between its electrode and a preceding scanning line in the previous row with using no extra masking procedure. The source, drain and gate electrodes of both the first and third TFTs are coupled to the same signal line, the electrode of the same pixel and the adjacent scanning lines, respectively. The gate, source and drain electrodes of the second TFT are coupled respectively to the same scanning line to which the gate electrode of the first TFT is coupled, the electrode of the same pixel and the electrode of a succeeding pixel provided on the opposite side of the scanning line to the same pixel. The arrangement also has a scanning driver circuit capable of activating two scanning lines at the same time for sequential one-by-one scanning operation, whereby no fault in a reproduced image will be perceived in spite of the presence of a defective TFT.
