Problems solved by technology

[0003] When a semi-transparent mask is used to make a columnar spacer, when the semi-transparent pattern of the mask exceeds a certain opening value, the light intensity at the center of the semi-transparent pattern will decrease compared with the light intensity at other positions , it is possible to form a crater-like depression on the top of the auxiliary spacer (please refer to figure 1 ), thus causing the risk of poor contact pressure of the LCD panel

Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.

[0056]The inventors of the present invention have found that when a semi-transparent film mask is used to make a columnar spacer, the light intensity at the center of the semi-transparent pattern is usually greater than that at other positions, and as the semi-transparent pattern increases, The difference between the light intensity at the center of the translucent figure and the light inte...

Abstract

The invention provides a mask, a display substrate, a manufacturing method of the display substrate and a display device. The manufacturing method of the display substrate comprises the following steps: an annular groove matched with a pre-arranged outer ring area at the top of an auxiliary spacer is formed in a film-layer pattern of the display substrate, so that the pre-arranged outer ring area at the top of the auxiliary spacer on the annular groove sinks; or a bulge matched with a pre-arranged middle area at the top of the auxiliary spacer is formed on the film-layer pattern of the display substrate, so that the pre-arranged middle area at the top of the auxiliary spacer on the bulge is lifted up; and therefore, the outer ring area and the middle area at the top of the auxiliary spacer are substantially in the same altitude, the top of the auxiliary spacer is prevented from a crater shape, the flatness of the top surface of the auxiliary spacer is improved, and contact-press-related unfavorableness of a liquid crystal display panel is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a mask, a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] The liquid crystal display panel part is mainly composed of an array substrate, a color filter substrate, and a boxed liquid crystal between them. In addition to providing a color-resisting layer for color filtering, the color filter substrate is also provided with a columnar spacer to support The LCD cell is thick. In order to make the film surface uniform after boxing and reduce the risk of low-temperature bubbles (Bubble) and gravity Mura, the columnar spacer is often set in two stages (main spacer (Main) / auxiliary spacer (Sub)) or Three-stage (Main / Sub1 / Sub2). In the prior art, mask designs for columnar spacers are mainly classified into conventional type and semi-permeable membrane type. Both the main spacer and the auxiliary spacer of the conventional columna...
