Problems solved by technology
[0003] The present application provides a display panel, a touch display device and a manufacturing method thereof, so as to solve the problem of being limited by the frame in the process of using side light to cure the frame glue in the existing box structure such as the display panel, etc. Factors such as the low reflectivity of light on the upper and lower sides of the glue, such as black retaining walls, make the curing rate and curing depth of the frame glue insufficient, resulting in the need for a larger frame glue width, which increases the frame width of box structures such as display panels. technical issues

Abstract
The present application proposes a display panel, a touch display device and a manufacturing method thereof. The display panel is provided with the first light-reflecting layer on at least one side of the first narrow-frame adhesive, so that it is convenient to light-cure the first narrow-frame adhesive. When the light is reflected by the first reflective layer, the penetration depth of the light is increased, thereby increasing the curing depth of the first narrow frame adhesive, improving the overall curing rate of the first narrow frame adhesive, and facilitating the use of smaller width The first narrow frame glue realizes the boxing of the display panel; realizes the narrow frame of the boxed structure such as the display panel, in the touch display device of the present application, through the second narrow frame between the display panel and the touch panel At least one side of the frame glue is set to the second reflective layer, which realizes the overall narrow frame of the touch display device, and the manufacturing process of this structure is mature, the method is simple, and the curing efficiency of the frame glue is high, which is convenient for the narrow frame touch display device. make.
Description
technical field [0001] The present application relates to the display field, in particular to a display panel, a touch display device and a manufacturing method thereof. Background technique [0002] With the development of display technology, narrow-frame large-size touch display has become the focus of the industry. The existing touch display is mainly composed of a display panel and a touch panel. In the box structure, the curing of the frame glue generally adopts the method of curing the frame glue on the side of the display panel with light, but it is limited by the light intensity and the reflection of light by structures such as black retaining walls on the upper and lower sides of the frame glue in the display panel. Low rate and other factors make the curing rate and curing depth of the frame glue insufficient, resulting in the need for a larger frame glue width to ensure the bonding of the upper and lower substrates into a box, and the change of direction increases...
