Abstract

The invention discloses a display device and a manufacturing method thereof, and belongs to the technical field of display. The display device comprises a first substrate and a second substrate which are oppositely arranged, wherein the side, which faces the second substrate, of the first substrate comprises a plurality of light-emitting elements; an adhesive layer is filled between the first substrate and the second substrate, and the first substrate and the second substrate are attached through the adhesive layer; and at least part of the adhesive layer extends to the edge position of the second substrate in the direction parallel to the plane where the first substrate is located. The manufacturing method of the display device is used for manufacturing the display device. The manufacturing method comprises the steps of providing a first substrate; sequentially arranging light-emitting elements and an adhesive layer on the first substrate; and providing a second substrate, wherein the first substrate and the second substrate are attached through the adhesive layer, and at least part of the adhesive layer extends to the edge position of the second substrate. According to the invention, the process steps are reduced, the manufacturing cost is reduced, the process efficiency is improved, and the product yield can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display device and a manufacturing method thereof. Background technique [0002] With the rapid development of wearable display devices, micro light emitting diode (Micro LED, uLED) and submillimeter light emitting diode (Mini LED) technologies have emerged. Both Micro LED technology and Mini LED technology belong to LED miniaturization and matrix technology, referring to a high-density micro-sized LED array integrated on a chip. The power consumption of Micro LED and Mini LED is much smaller than that of Liquid Crystal Display (LCD), and they are self-illuminating like Organic Light-Emitting Diode (OLED), which can reduce the distance between pixels from millimeters to At the micron level, the color saturation is close to OLED, so many manufacturers regard Micro LED and Mini LED as the next-generation display technology. [0003] The display device of LED m...
