Abstract
A reflective type IPS LCD includes a transparent upper substrate (100) and a lower substrate (200), and liquid crystal molecules (300) interposed between the substrates. A reflection layer (250) is disposed on the lower substrate. A plurality of gate lines (170) and a plurality of data lines (180) are formed on the upper substrate, thereby defining a plurality of pixel regions arranged in a matrix. Each pixel region includes pixel electrodes (210) and common electrodes (220). The pixel electrodes and the common electrodes have a bent configuration, and are spaced apart from each other. Therefore the electric field generated by them is along two directions, and the LCD exhibits a two-domain display effect. When viewing the LCD display from any oblique angle, the color shifts generated by the two domains counteract, and thus the overall color shift of the display is small.
