Abstract

The invention discloses a mask plate, a production method thereof, a display substrate, a packaging method thereof and a display device and relates to the technical field of the mask plate. The problem that in a packaging process of a display device, a packaging effect of the display device is influenced due to relatively thick under coating is solved. The mask plate comprises a mask frame and a plurality of mask strips set on the mask frame. The mask strips comprise first mask strips stretching along a first direction and second mask strips stretching along a second direction. The first maskstrips and the second mask strips are crossly set and define a plurality of opening areas. The opening areas are used for forming film patterns. Convex stopper structures are set on the mask strips atthe side facing to-be-formed film. The mask plate provided by the invention is used for packaging the display device.

Description

technical field [0001] The present invention relates to the technical field of mask plates, in particular to a mask plate and a manufacturing method thereof, a display substrate and a packaging method thereof, and a display device. Background technique [0002] With the continuous development of display technology, Organic Light-Emitting Diode (English: Organic Light-Emitting Diode, hereinafter referred to as OLED) display devices are gradually receiving attention due to their characteristics such as self-luminescence, high brightness, wide viewing angle, high contrast, flexibility, and low energy consumption. people's widespread attention. This OLED display device is made of a thin organic material coating and a glass substrate. When a current passes through, the organic material in the OLED display device will emit light, thereby realizing the display function of the OLED display device. [0003] Since organic materials in OLED display devices are prone to react with wate...
