Abstract

The invention discloses a display device and a manufacturing method thereof, and belongs to the technical field of liquid crystal display. The display device comprises a display panel, a cover plate and a liquid glue layer, wherein the display panel and the cover plate are in opposite arrangement; the liquid glue layer is arranged between the display panel and the cover plate; the display panel and the cover plate are attached through a rubber frame; the rubber frame at least comprises a first rubber frame and a second rubber frame; the first rubber frame and the second rubber frame are in concentric arrangement; a first narrow seam is formed between the first rubber frame and the second rubber frame; at least one first notch is formed in the first rubber frame; through the arrangement ofthe multilayer rubber frame, the narrow seam is formed between the rubber frames; the notch is formed in the rubber frame; during pressing operation, excessive liquid glue can enter the narrow seam region from the notch; air inside the display device can be exhausted through the narrow seam region; the requirements on production environment are not high; the notches of multilayer rubber frames areformed in different sides; through the multilayer rubber frames, water steam is prevented from entering the inside of the display device from the use environment of the display device; the problem ofshort service life of the display device is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a fully laminated display device and a manufacturing method thereof. Background technique [0002] Liquid crystal display products are widely used in daily life. With the popularization in daily life, the demand for products is large. The yield rate of liquid crystal display products is directly related to the production cost and sales of enterprises. [0003] The bonding of the liquid crystal display device is an important part of the manufacturing process, and two or three of the display panel, the touch layer, and the protective cover can be bonded together. At present, there are frame stickers and full fit methods that are common. The frame sticking method coats the glue with word graphics around the display panel, and glues the display panel and the cover plate together after curing. This method is simple to operate but will form an air layer between the disp...
