Liquid crystal display device

A liquid crystal display device, comprising:

• an active matrix substrate;
• a color filter substrate including a transparent substrate and a color filter layer;
• 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 region and a second transparent dielectric region both defined in the reflection region;
• the first transparent dielectric region is provided on the transparent substrate and at least partially surrounded on at least two sides by the color filter layer;
• the second transparent dielectric region is provided on the color filter layer and adjacent to the first transparent dielectric region;
• and
• a thickness d1 of the first transparent dielectric region is larger than a thickness d2 of the second transparent dielectric region.
