Mask board and photo-alignment method

Abstract

The invention discloses a mask board. The mask board comprises light-transmitting patterns arranged on a mask board body, and each pattern comprises a light-transmitting region and a shading region, wherein the area of the light-transmitting region and the area of the shading region of the light-transmitting pattern in the position of a central line of the mask board body are equal, and in the left side region from the central line of the mask board body to the left side boundary of the mask board body, the areas of the light-transmitting regions of the light-transmitting patterns gradually increase leftwards from the central line, and the areas of the shading regions gradually decrease leftwards from the central line; in the right side region from the central line of the mask board body to the right side boundary of the mask board body, the areas of the light-transmitting patterns gradually increase right wards from the central line, and the areas of the shading regions gradually decrease rightwards from the central line. The mask board enables areas of a left region and a right region which are close to the outside to gradually increase, and the area of the left region and the right region which are close to the inside to gradually decrease by dividing a sub-pixel into the left region and the right region, so that when a panel is bent, pixel inequality of the regions on the two sides of the panel is compensated, and the problem of color cast increasing on the two sides of the panel is solved.

Description

technical field [0001] The invention belongs to the field of liquid crystal display devices, in particular to a mask plate and an optical alignment method. Background technique [0002] The liquid crystal display device has many advantages such as thin body, power saving, and no radiation, and has been widely used. In recent years, curved liquid crystal displays have gradually become popular. The curved design of the display panel of the curved liquid crystal display is surrounded by the direction of the user, which can provide a wide panoramic image effect, whether it is in the center of the screen or around the edge, it can bring the same visual enjoyment , and also reduces distortion for off-axis viewing when viewing at close distances. In addition, the curved liquid crystal display device can lengthen the viewing distance of the user to achieve a better viewing experience. Therefore, compared with ordinary liquid crystal display devices, curved liquid crystal display d...
