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.

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).

In an OCB liquid crystal display device, a gradation voltage of a video signal is set to be lower than a black display optimum voltage, and a reverse transition prevention voltage is set to be higher than the black display optimum voltage and to be lower than a maximum applied voltage, and as the gradation voltage of the video signal becomes low, the reverse transition prevention voltage is set to be high.

摘要:
A liquid crystal display device comprises an OCB-mode liquid crystal display panel including a liquid crystal layer in which the alignment state of liquid crystal molecules is transitioned in advance from a splay alignment to a bend alignment, and a display control section which applies a liquid crystal drive voltage to the liquid crystal layer according to a video signal. The display control section is configured to detect the application environment of the liquid crystal display panel and determine a minimum value of the liquid crystal drive voltage based on a phase-transition threshold voltage which causes energy of the splay alignment and energy of the bend alignment to be balanced with each other in the detected application environment.
