Patent ID: 7030948

Claim:
A liquid crystal display device, comprising: an active matrix substrate: a color filter substrate including a transparent substrate and a color filter layer located closer to the active matrix substrate than the transparent substrate; a liquid crystal layer provided between the active matrix substrate and the color filter substrate; and a picture element region including a transmission region in which an image is displayed in a transmission mode, and a reflection region in which an image is displayed in a reflection mode, wherein: a thickness of the liquid crystal layer is less in the reflection region than in the transmission region; a height of a surface of the color filter substrate on a side closer to the liquid crystal layer in the reflection region is greater than that in the transmission region; the color filter substrate includes a first transparent dielectric layer formed on the transparent substrate and covered or surrounded by the color filter layer, and a second transparent dielectric layer provided in the reflection region so as to be located closer to the liquid crystal layer than the first transparent dielectric layer and the color filter layer; the first transparent dielectric layer is formed between the transparent substrate and the color filter layer and is covered by the color filter layer; and the color filter layer in the reflection region is made of a material that is different from that of the color filter layer in the transmission region.
