摘要： Optical compensation elements include first phase plates and second phase plates, which have retardation in a front-plane direction. When a value Δn/Δnλ is set by normalizing a retardation amount Δn·d relating to light of each of wavelengths by a retardation amount Δnλ·d relating to light of a predetermined wavelength λ, a normalized value Δn/Δnλ in the first phase plate is greater than a normalized value Δn/Δnλ in a liquid crystal layer, and a normalized value Δn/Δnλ in the second phase plate is less than the normalized value Δn/Δnλ in the liquid crystal layer, with respect to light of wavelengths other than the predetermined wavelength.

摘要： A liquid crystal display device includes an OCB mode liquid crystal display panel, and an optical compensation element which is disposed outside of the liquid crystal display layer. The optical compensation element includes a polarizer plate, a first retardation plate which is disposed between the polarizer plate and the liquid crystal layer, and a second retardation plate which is disposed between the polarizer plate and the first retardation plate and has a biaxial refractive index anisotropy. The optical compensation element compensates a difference of a polarization state that differs between azimuth directions of light passing through the liquid crystal layer and compensates a shift of the polarization state of light, which passes through the retardation plate, from an azimuth direction of an absorption axis of the polarizer plate.

摘要： It is possible to eliminate the blue tone in the black color display in the OCB liquid crystal display device. A liquid crystal display cell (110) includes an opposing substrate (130) having an opposing electrode (Ecom), an array substrate (120) having pixel electrodes of the respective colors (dpixR, dpixG, dpixB), a liquid crystal layer (140) arranged in a bend-arrangement and sandwiched between the opposing substrate (130) and the array substrate (120), and red, green, and blue filter layers (CF(R), CF(G), CF(B)) arranged on one of the substrates. The maximum voltage is applied when performing black color display on the display screen. At least the maximum voltage of the pixel electrode for blue color dpixB applied to the opposing electrode (Ecom) is made different from the maximum voltage of the pixel electrodes of the other colors applied to the opposing electrode (Ecom).
