Abstract: A display panel and a display device are disclosed. In preparing the display panel, based on a height difference formed between a plurality of first column spacers and a plurality of second column spacers, as a color filter substrate deforms during a vacuum assembly process, a deformation area of a blind hole area increases because the second column spacers are not in contact with an array substrate in the blind hole area, resulting in a decrease in a radius of curvature of the deformation of the blind hole area, so that an amount of deformation is reduced and poor focusing due to Newton's ring effect on the blind hole can be prevented.

Abstract: The present disclosure provides a cover, a display device, and a method for manufacturing the display device. By forming a first via hole in an electronic component disposing region when an optically clear adhesive is formed on the cover, via holes are formed because the optically clear adhesive cannot form in the electronic component disposing region. Thus, the optically clear adhesive does not have portions having different thicknesses, thereby preventing bubbles from forming in a blind hole region, and solving technical problems of the existing display device that the OCA has bubbles around the corresponding blind hole region, which affects photographing quality.
