Abstract

The invention discloses a display device and a cover plate thereof, wherein the cover plate of the display device comprises a transparent base plate, a first ink layer and a second ink layer; the transparent base plate comprises a display region positioned in the center and a non-display region surrounding the periphery of the display region; the first ink layer is arranged at the inner side surface of the non-display region of the transparent base plate; the second ink layer is arranged on one side, far away from the transparent base plate, of the first ink layer; the area of the second ink layer is smaller than the area of the first ink layer; a step part is formed between the second ink layer and the first ink layer; a hollow part is arranged at one side edge, near the display region, of the second ink layer; the hollow part communicates with the step part; and the hollow part is used for exhausting. The display device and the cover plate of the display device have the advantages that through the arrangement of the hollow part at one side, near the display region, of the second ink layer, the exhaust area can be increased; and the problem of display region attaching bubbles caused by ink misplacing can be solved.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a display device and its cover plate. Background technique [0002] At present, the top of the display panel of the display has a cover plate, the cover plate includes a display area located in the middle, a non-display area located on the periphery of the display area, and an ink layer printed on the non-display area. In the manufacturing process of the display panel, it is necessary to apply an ink layer on the non-display area of ​​the inner wall of the cover in advance, and then apply an OCA optical adhesive layer on the inner surface of the display area and the ink, and stick the cover plate through the OCA optical adhesive layer on the display panel. However, due to the existence of the ink layer, there is an ink gap between the display area and the non-display area of ​​the cover. When the OCA optical glue is attached to the display area and the ink layer, there w...
