Display panel, manufacturing method thereof, alignment layer coating device and display device

Abstract

The invention discloses a display panel, a manufacturing method thereof, an alignment layer coating device and a display device and belongs to the technical field of liquid crystal display. The method comprises steps as follows: first alignment layers are formed in a display area, a non-display area and a peripheral area of a first substrate; roll printing operation is performed on the first alignment layers formed in the first substrate, and first alignment films are formed; second alignment layers are formed in areas, except the target areas, of a display area, a non-display area and a peripheral area of the second substrate, and the target areas are used for arrangement of leads electrically connected with a drive circuit; roll printing operation is performed on the second alignment layers formed in the second substrate, and second alignment films are formed; the first substrate and the second substrate which are subjected to buckling are cut, and the display panel is obtained. The problem of poorer display effect of the display panel is solved, the display effect is improved, and the display panel is used for the display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel and a manufacturing method thereof, an alignment layer coating device and a display device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has been widely used due to its thin body, power saving, and no radiation. Examples are LCD TVs, mobile phones, personal digital assistants, digital cameras, computer screens or laptop screens, etc. [0003] The display panel of the liquid crystal display device includes a color filter substrate, an array substrate disposed opposite to the color filter substrate, and a liquid crystal layer filled between the color filter substrate and the array substrate. see figure 1 , the formation process of the color filter substrate mainly includes: sequentially forming a red-green-blue (red-green-blue, RGB) resin layer 2, a flat layer 3, and a polyimide (polyimide, PI) coating on the ...
