ABSTRACT:
To reduce the blue tone in the black display of the OCB liquid crystal display device. A liquid crystal display cell (11) includes: an opposing substrate (130) having an opposing electrode (Ecom); an array substrate (120) having a pixel electrode Dpix for each color; a liquid crystal layer (140) arranged in a bend arrangement located between the opposing substrate (120) and the array substrate (120); and red, green, and blue filter layers arranged on one of the substrates. The opposing electrode has a film thickness tB of the portion Ecom (B) corresponding to the blue filter layer, which thickness is set so as to have the minimum value in the range 380 nm to 480 nm in the spectrum of the front reflectance and satisfy the following: 100 nm<tB≦140 nm.
