摘要： The present invention realizes an IPS liquid crystal display device which exhibits small directivity of viewing angle and high brightness. Below a pixel electrode having a comb-teeth-shaped electrode and having a laterally-extending trapezoidal profile, a planar common electrode not shown in the drawing is formed by way of an insulation film. When a video signal is applied to the pixel electrode, an electric field is generated between the pixel electrode and the common electrode via slit portions formed in the pixel electrode thus controlling liquid crystal molecules. The pixel electrodes are arranged in a packed state by alternately reversing the direction of the trapezoidal shape in the longitudinal direction. Since a light blocking film is not present between two pixel electrodes arranged adjacent to each other in the longitudinal direction, the liquid crystal display device can acquire high transmissivity. As a result, a liquid crystal display device having high brightness can be realized.

摘要： A liquid crystal display apparatus includes a transmissive display portion having the same liquid crystal alignment directions and transmissive axes of the polarizers as the transmissive IPS liquid crystal display apparatus. Further, the liquid crystal layer of its reflective display portion has a retardation of a quarter wave. The liquid crystal alignment directions of the reflective display portion are set to be crossed with the transmissive axes of the polarizers in the transmissive display portion at an angle of 45 degrees.

摘要： A liquid crystal display device includes pixels A and pixels B, wherein a width BB of the pixel B is smaller than a width AA of the pixel A. A pixel electrode formed in the pixel B is smaller than a pixel electrode formed in the pixel A in area and hence, capacitance formed between the pixel electrode and a counter electrode which is formed below the pixel electrode with an insulation film sandwiched therebetween becomes small. To eliminate this difference in capacitance, a first branch electrode and a second branch electrode are formed on the pixel electrode of the pixel B thus increasing capacitance between the pixel electrode and the counter electrode. Due to such a constitution, it is possible to prevent the deterioration of image quality attributed to imbalance of capacitance.
