Abstract
A liquid crystal panel with a uniform background color has a pixel region that actually generates images on the liquid crystal panel and is defined as an active area. Another region that does not generate images is defined as a viewing area. A black matrix in the viewing area has multiple windows so that the viewing area and the active area have the same or similar reflection regions. Therefore, the liquid crystal panel has a uniform background color.
