Abstract

The invention provides a multi-domain vertical alignment type display panel and pixel structure. The pixel structure comprises three sub-pixels arranged in parallel, wherein each sub-pixel comprises an upper alignment domain and a lower alignment domain; each of the upper and lower alignment domains comprises four sub-domains, and alignment directions of the vertically adjacent sub-domains and horizontally adjacent sub-domains of the four sub-domains are mutually perpendicular; the alignment directions of any two adjacent sub-domains located in the vertically adjacent and horizontally adjacent sub-pixels are the same; the alignment directions of any two adjacent sub-domains located in the upper and lower alignment domains which are vertically adjacent are the same, dark lines can be reduced, and the light transmittance is improved.

Description

【Technical field】 [0001] The invention relates to a display panel and a pixel structure thereof, in particular to a display panel with multi-region vertical alignment induced by ultraviolet rays and a pixel structure thereof. 【Background technique】 [0002] Thin film transistor liquid crystal (TFT-LCD) displays have been developed rapidly and widely used in recent years. Specifically, TFT-LCD can be regarded as a layer of liquid crystal sandwiched between two glass substrates, the upper glass substrate is a color filter, and the lower glass substrate is provided with a thin film transistor. When the current passes through the thin film transistor, a change in the electric field is generated, and the change in the electric field causes the liquid crystal molecules to deflect, thereby changing the polarity of the light and realizing the expected display screen. Before the voltage is applied, the liquid crystal molecules need to have an initial alignment direction. Therefore, ...
