Provided is a liquid crystal display device including: a first substrate; a second substrate opposite to the first substrate; and a liquid crystal layer between the first substrate and the second substrate, and includes pixels arranged in a matrix pattern. The pixels each include a reflective region in which display is provided in a reflective mode and a transmissive region in which display is provided in a transmissive mode. At least one of the pixels further includes a light blocking region inside the transmissive region. The second substrate includes a second substrate side insulating layer and a color filter layer sequentially toward the liquid crystal layer. The second substrate side insulating layer is placed in the reflective region and the light blocking region. A film thickness of the color filter layer in the transmissive region is greater than a film thickness of the color filter layer in the reflective region.

Liquid crystal display device

The liquid crystal display device includes: a first polarizer having a first transmission axis; a liquid crystal panel; a second polarizer having a second transmission axis; a biaxial retarder having a slow axis parallel to the second transmission axis; a third polarizer having a third transmission axis parallel to the second transmission axis; and a backlight, a back side polarizer portion that includes the second polarizer, the biaxial retarder, and the third polarizer satisfying the following formula (1): &#x394;YI=YI'&#x2212; YI&#x3c;0 (1) wherein YI&#x2032; represents a yellowness index in observation from an oblique direction, YIrepresents a yellowness index in observation from a front direction, and &#x394;YIrepresents a difference between YI&#x2032; and YI, wherein the front direction represents a direction at a 0&#xb0; polar angle and the oblique direction represents a direction at a 60&#xb0; polar angle and a 45&#xb0; azimuth.
