Abstract
In a SW-LCD, an orienting film is divided into first and second regions having different directions of orientation, and a transparent electrode film is also patterned so as to be divided into regions respectively corresponding to the first and second regions. In the first region, a viewing angle in right and left directions is controlled. In the second region, a viewing angle in upper and lower directions is controlled. With this, a display device is realized which makes it possible to switch between a wide viewing angle display mode and a narrow viewing angle display mode, which controls a viewing angle in both upper and lower directions and in right and left directions in the narrow viewing angle display mode, and which makes it possible to prevent an image from being seen obliquely from the right and left directions and from the upper and lower directions.
