Multiple zone vertical arranged liquid crystal display board

Abstract

The multiple zone vertically arranged LCD board includes one upper base board, one lower base board, one conducting layer between the upper base board and the lower base board, one liquid crystal molecule layer filled between the conducting layer and the lower base board, the first protrusions set in the conducting layer surface opposite to the lower base board and the second protrusions set in the lower base board surface opposite to the upper base board to orient the liquid crystal molecules, and mask patterns in the upper base board surface opposite to the lower base board and in the positions corresponding to the first protrusions to block the light leakage of the first protrusions.

Description

technical field [0001] The present invention relates to a multi-domain vertical alignment (multi-domain vertical alignment, MVA) liquid crystal display panel, in particular to a multi-domain vertical alignment liquid crystal display capable of avoiding light leakage at the edge of alignment protrusions plate. Background technique [0002] Liquid crystal displays have been widely used in various electronic products, such as mobile phones, personal digital assistants (PDAs) and notebook computers (notebooks), and with the rapid development of the large-size flat-panel display market, liquid crystal Display plays a very important role, and gradually replaces cathode ray tube (CRT) display to become the mainstream of the market. However, the limited viewing angle of the liquid crystal display has become a limiting condition for development. Therefore, a multi-area vertically aligned liquid crystal display panel that can increase the viewing angle has emerged as the times requir...

Problems solved by technology

[0005] As mentioned above, although the multi-area vertically aligned liquid crystal display panel in the prior art has a wide viewing angle, due to the alignment protrusions, some liquid crystal molecules will rotate slightly without applying a voltage, especially those located on the alignment protrusions. The liquid crystal molecules near the object will cause light leakage on the liquid crystal display panel and reduce the contrast of the liquid crystal display, thereby affecting the display effect of the liquid crystal display

For example, when a certain pixel area needs to display a complete black, theoretically the red, green and blue sub-pixels in the pixel area should be in a completely dark state, but when light leakage occurs, the ideal complete black cannot be displayed. resulting in poor contrast

Or when the color displayed in a certain pixel area only needs to use a combination of red and green, the light leakage in the blue sub-pixel area will cause the pixel area to fail to show the required color, thus affecting the display effect of the LCD
