Problems solved by technology
However, during the process of separating the flexible substrate and the carrier substrate, the ultraviolet light used for separation may damage the display elements in the flexible display
On the other hand, the production process of some flexible displays involves the step of using ultraviolet light to cure the frame glue. However, since the ultraviolet light will pass through the flexible substrate and then irradiate the frame glue, the material of the flexible substrate will affect the UV light. The effect of curing the frame glue, some flexible displays will have the problem of incomplete curing of the frame glue

Abstract
The invention discloses a liquid crystal display and a manufacturing method thereof. The liquid crystal display comprises a first flexible substrate, a display structure, a frame glue, and a second flexible substrate. The display structure is located on the first flexible substrate. The frame glue surrounds side surfaces of the display structure. The second flexible substrate is located on the frame glue and the display structure. One of the first flexible substrate and the second flexible substrate comprises a first flexible material layer and a second flexible material layer. The second flexible material layer is interposed between the first flexible material layer and the display structure, and part of the layer surrounds the side surfaces of the first flexible material layer and overlaps the frame glue. The ultraviolet light transmittance of the second flexible material layer is higher than the ultraviolet light transmittance of the first flexible material layer. In the process ofmanufacturing the liquid crystal display, the above structural design can make the curing degree of the frame glue to be good, when the frame glue is cured with ultraviolet light; and the above structural design can make the display structure not that easily damaged by the laser, and the lift-off yield is high, when the laser lift-off is performed.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a liquid crystal display (Liquid crystal display, LCD). Background technique [0002] In recent years, with the continuous development of display technology, a flexible display (Flexible display) has been developed in the field of display technology, which has the characteristics of thinness, flexibility and impact resistance, and has a wide range of applications. [0003] Generally speaking, the manufacturing method of the flexible display is to fix the flexible substrate on the carrier substrate first, and then manufacture the display elements on the flexible substrate. After the display element is manufactured and the flexible display is formed, the carrier substrate is removed. However, in the process of separating the flexible substrate and the carrier substrate, the ultraviolet light used for separation may damage the display elements in the flexible display. On ...
