Patent ID: 6850298

Claim:
A liquid crystal display device, comprising: a first substrate; a second substrate; a liquid crystal layer provided between the first substrate and the second substrate; and a plurality of picture element regions for displaying an image, wherein: at least one of the plurality of picture element regions includes a transmission region in which an image is displayed in a transmission mode by using light that is coming from a side of the first substrate, and a reflection region in which an image is displayed in a reflection mode by using light that is coming from a side of the second substrate; a height of a surface of the second substrate on a side closer to the liquid crystal layer in at least part of the reflection region is greater than that in the transmission region; while a height of a surface of the first substrate on a side closer to the liquid crystal layer in the reflection region is substantially equal to that in the transmission region; the second substrate includes a color filter layer provided in the transmission region and in the reflection region; a thickness of the color filter layer in at least a portion of the reflection region is smaller than that in the transmission region; the second substrate includes a transparent substrate, and a first transparent dielectric layer formed between the transparent substrate and the color filter layer in at least a portion of the reflection region; and the color filter layer is provided on one side of the second substrate that is closer to the liquid crystal layer; and a second transparent dielectric layer is formed on the color filter layer in the reflection region.
