摘要： PROBLEM TO BE SOLVED: To improve the display quality by making a common electrode low in resistance and reducing reflected light from a light shield member, and preventing switching characteristics from decreasing and the voltage of the common electrode from varying. SOLUTION: While reflected light of a light shield film 24 is reduced by interposing an insulating film 46 between the light shield film 24 and common electrode 50 to prevent characteristics of a TFT 22 from decreasing owing to a light leak current, the coupling capacity between the light shield film 24 and common electrode 50 is increased and then the resistance value of the common electrode 50 is reduced by electrically connecting the light shield film 24 and common electrode 50 to each other at the peripheral part of a display area 'A' to prevent the potential of the common electrode 50 from varying owing to coupling with a signal line, thereby suppressing an uneven display due to crosstalk, etc.

摘要： PURPOSE:To provide the liquid crystal display device which can reduces a display irregularity due to a difference in resistance value among lead-out electrodes. CONSTITUTION:A transparent electrode pattern 31 of ITO is formed as a transparent electrode on the lead-out electrodes 14, connected to an external connection terminal 15, across liquid crystal. The area of the transparent electrode pattern 31 which faces the lead-out electrodes 14 is made small at the position facing the lead-out electrodes 14 which are long in overall length and large at the part facing the lead-out electrodes 14 which are short in overall length. Small liquid crystal capacity is formed at the part where the overall-length resistance value of the lead-out electrodes 14 is large and small liquid crystal capacity is formed at the part where the overall-length resistance value of the lead-out electrodes 14 is small. Even when the lead-out electrodes 14 differ in length to differ in resistance value, the impedance values obtained by adding the resistance values of the lead-out electrodes 14 and the liquid crystal capacity of the lead-out electrodes 14 and transparent electrode pattern 31 are made constant. The display irregularity due to the difference in resistance value among the lead-out electrodes 14 is reduced.

摘要： PURPOSE:To make it possible to mixedly mount a circuit which is strong in electrostatic breakdown and weak in noise and a circuit which is liable to generate noise, by connecting, via a resistance element, different pins for supplying a first electric potential to a first and a second circuits. CONSTITUTION:Noise generated from a circuit 23 travels to a circuit 22 via a resistance element 31. The power supply of a first circuit 22 and the ground are generally provided with a capacitor of several hundreds pF or more. The noise is attenutated by the effect of RC delay due to said capacitor and the resistance element. When a high voltage caused by static electricity is applied across the signal pad 24 of the circuit 22 and a power supply pad 29 of the circuit 23 or the ground pad 30, electric charge is discharged to the power supply pad 29 or the ground pad 30 through an input protecting circuit in the circuit 22 and the resistor 31. As a result, a high voltage is not applied to transistors in the circuit 23, so that these transistors are protected from electrostatic breakdown.
