Title:
TFT TYPE LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3308100
Kind Code:
B2
Abstract:
PURPOSE: To improve an opening rate and to improve lightness by providing the device with first and second wirings formed of transparent electrodes, shielding films and pixel electrodes.
CONSTITUTION: The plural parallel board band-shaped gate wirings 2 which consist of an ITO (indium tin oxide) as a transparent metal and spread nearly over the entire surface of the display regions of unit pixels are formed in one direction on the one glass 1. The plural parallel broad band-shaped source wirings 3 which consist of the ITO as well are laminated and formed via first insulating films 4 consisting of SiO2 in a direction orthogonal with the respective gate wirings 2. Shielding films 6 are formed of the ITO as well in the source wirings 3 via second insulating films 5 consisting of SiO2. Recessed parts 9 formed to a recessed shape in plane view are formed near the parts intersecting with one edge of the data wirings 2 at the edges on one side of the respective source wirings 3. TFTs 10 corresponding to the respective pixel electrodes 8 are formed in the respective recessed parts 9.
