    摘要: An in plane switching liquid crystal display (2) includes a first substrate (27), a second substrate (37) and a liquid crystal layer (23) having a plurality of liquid crystal molecules. A number of pixel electrodes (25) and common electrodes (24) are formed on the first substrate, and each of the pixel electrodes and common electrodes include at least two bend portions (241, 242, 243). Each bend portion has a first side and a second side. An original alignment direction of the liquid crystal molecules form at least two different angles with the sides of the bend portions of the common and pixel electrodes. When a voltage is applied to the pixel electrodes and the common electrodes, the liquid crystal molecules are aligned along at least three different directions. Therefore, the IPS-LCD can have uniform viewing performance at different viewing angles.

    摘要: 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.

    摘要: A continuous domain vertical alignment liquid crystal display (2) has a first substrate (21), a second substrate (22), and liquid crystal molecules (26) interposed between the substrates. A plurality of curved slits (211) and a plurality of curved protrusions (221) are disposed at insides of the substrates respectively. When an electric field is applied between the substrates, the liquid crystal molecules are inclined to be oriented parallel to the substrates. In addition, the curved slits and the curved protrusions affect the orientations of the liquid crystal molecules, such that the liquid crystal molecules are directed to incline in various directions in smooth continuums. The visual effect of the continuous domain vertical alignment liquid crystal display is the sum of multiple smooth continuous domains. Thus the continuous domain vertical alignment liquid crystal display provides a more even display performance at various different viewing angles.
