Problems solved by technology

[0005] In view of this, the embodiment of the present invention provides a mask plate and an alignment film rubbing method to solve the problem of orientation of the rubbing cloth on the rubbing roller passing through the non-display area in the prior art due to the unevenness of the non-display area. Damage, which in turn causes the problem of friction angle deviation in the friction direction

Embodiment Construction

[0034] The specific implementation of the mask plate and alignment film rubbing method provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] The shape and size of each film layer in the drawings do not reflect the true proportion of the mask, but are only intended to schematically illustrate the content of the present invention.

[0036] A mask plate provided by an embodiment of the present invention, such as Figure 2a and Figure 2b As shown, the mask plate 01 is used to cover the non-display area of ​​the substrate 02 when rubbing the alignment film on the substrate 02;

[0037] The mask plate 01 includes at least one backing plate 011; wherein,

[0038] One side of the backing plate 011 is a horizontal plane, and the other side has at least a pattern matching the partial pattern of the non-display area at the covering position;

[0039] The thickness of the backing plate 011 at the ...

Abstract

The invention discloses a masking plate and an orientation film friction method. The masking plate comprises at least one cushion plate, one side of the cushion plate is a horizontal plate, and the other side of the cushion plate is provided with graphs matched with partial graphs of a non-display area of the coverage position; the thickness of the contact position of the side of the cushion plate with the graphs and a substrate is equal to the distance between the surface of the non-display area and the surface of a display area at the contact position, and the cushion plate is used for covering the non-display area of the substrate when an orientation film on the substrate is subjected to friction, so that the surface of the non-display area at the coverage position is flush with the surface of the display area, orientation damage to friction cloth at the corresponding position caused by unevenness of the surface of the non-display area when the orientation film is subjected to friction is avoided, and thus friction angle error in the friction direction and abnormal orientation of the orientation film are avoided, and display uniformity of display products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a mask plate and an alignment film rubbing method. Background technique [0002] In recent years, liquid crystal display panels (Liquid Crystal Display, LCD) have gradually spread in people's lives. A liquid crystal display panel is mainly composed of an array substrate, a color filter substrate, and liquid crystal molecules located between the two substrates. The liquid crystal display panel controls the orientation of liquid crystal molecules through an electric field to change the transmittance of the liquid crystal display panel, thereby realizing the display function. In order to arrange the liquid crystal molecules in a certain direction in the initial state, it is necessary to coat a layer of alignment film on the inner surface of the opposite substrate of the liquid crystal display panel and the inner surface of the array substrate, and then use a rubbing ...
