Liquid crystal display pixel structure and manufacturing method thereof

Abstract

The invention provides a liquid crystal display pixel structure and a manufacturing method thereof. The liquid crystal display pixel structure comprises a lower substrate (1), a passivation layer (2), pixel electrodes (3), an upper substrate (4) and a common electrode (5), the passivation layer (2) is arranged on the upper surface of the lower substrate (1), the pixel electrodes (3) are arranged on the passivation layer (2), the common electrode (5) is arranged on the lower surface of the upper substrate (4), each pixel is provided with multiple domains; within one pixel, the passivation layer (2) comprises at least two groove structures different in depth, the pixel electrodes (3) continuously cover the groove structures, and the groove structures different in depth divide one pixel into different areas, so that liquid crystals of different areas in one pixel can produce different deflection angles under the same driving voltage. The liquid crystal display pixel structure can improve color cast under big viewing angle remarkably, driving of a control circuit is simple, and aperture rate of the pixels is high.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display pixel structure and a manufacturing method thereof. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or notebook computer screen, etc., occupy a dominant position in the field of flat panel display. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a housing, a liquid crystal display panel disposed in the housing, and a backlight module disposed in the housing. The liquid crystal display panel is the main component of the liquid crystal display, but the liquid crystal display panel itself does not emit light, and needs the light source provided by the bac...

AI Technical Summary

Problems solved by technology

like Figure 4 , Figure 5 As shown, the above-mentioned liquid crystal display pixel structure has only one rotation behavior of liquid crystal in each pixel under the same driving voltage, so the liquid crystal deflection angle Θ is the same, although each pixel is set to four domains for color shift under large viewing angle There is some improvement, but the effect is not good, and the color cast is still serious
