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.

The pixel electrodes and the common electrodes have a same curved shape, and are uniformly spaced apart from each other. Therefore the electric field generated by them is a smooth continuum of multiple domains, and the visual performance at various different viewing angles is equally good. Because the pixel and common electrodes do not have sharp bends, disclination is avoided. Therefore the IPS liquid crystal display has a high contrast ratio.

Abstract: A color filter (30) includes a black matrix (33), and the black matrix has a first antireflection layer (331) and a second antireflection layer (332) on the first antireflection layer. Each antireflection layer includes a first antireflection film (3311, 3321) having a first refraction index, and a second antireflection film (3312, 3322) having a second refraction index which is different to the first refraction index. Because of so-called destructive interference of outside source light beams reflected from various interfaces defined by the first and second antireflection films, net reflection of the light beams by the black matrix back to an outside of the color filter is minimal. For similar reasons, net reflection of internal source light beams by the black matrix back to an inside of the color filter is minimal. As a result, visibility of a liquid crystal display device (300) employing the color filter is improved.
