Abstract
Provided is a liquid crystal display device which has a structure, in which a light shielding film is disposed on a color filter substrate corresponding to a position facing a TFT, and among a plurality of colored layers which form the color filter, a blue-colored layer and colored layers of colors other than blue are laminated on the light shielding film. With the structure as described above, the laminated colored layers reduce light which enters the TFT, and hence a leak current of the TFT can be prevented from occurring. Accordingly, a contrast or display quality of the liquid crystal display device can be prevented from deteriorating.
Claims6
A liquid crystal display device, which performs color display using a blue display pixel and display pixels for colors other than blue, comprising:
- a substrate including a TFT formed thereon;
- a counter substrate including a color filter formed thereon, the color filter including a blue-colored layer and colored layers of colors other than blue;
- a liquid crystal layer disposed in a gap formed between the substrate and the counter substrate;
- and
- a light shielding film having light shielding property, which is formed at a position facing the TFT of the counter substrate,
- wherein the blue-colored layer and the colored layers of colors other than blue are laminated on the light shielding film corresponding to the display pixels for colors other than blue.
