Abstract: A backlight module and a liquid crystal display are provided. The backlight module has a substrate, a plurality of soldering pads, and a reflective pattern layer. The soldering pads are distributed on the substrate and each of the soldering pads has a soldering pad size. The reflective pattern layer covers the soldering pads and the substrate. The reflective pattern layer has openings, positions of the openings correspond to positions of the soldering pads, each of the openings has an opening size, and the opening size is smaller than the corresponding soldering pad size. The backlight module is provided with the openings in the reflective pattern corresponding to the positions of the soldering pads, and the opening size of the openings is smaller than the soldering pad size of the soldering pads, thereby increasing a ratio of the reflective pattern layer to the substrate. Therefore, brightness is improved.

Abstract: An array substrate, a manufacturing method thereof, and display panel are provided. Gate scanning lines and Light-shielding conductive layer are electrically connected, so that a width of the gate scanning line is substantially unchanged from the conventional technology to ensure an aperture ratio of a display panel. Therefore, an impedance of the wire used to transmit the scanning electrical signal is reduced, so that the display panel driving power consumption is reduced to increase the corresponding speed of pixel charging and discharging.

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.
