The display panel has a first bonding surface, the first bonding surface includes a display area and a non-display area, the non-display area surrounds the display area, wherein two adjacent sides of the first bonding surface Between the edges There is a first angle. The touch panel has a second bonding surface, and the second bonding surface faces the first bonding surface of the display panel. An adhesive layer is disposed between the first bonding surface and the second bonding surface, and adheres the touch panel and the display panel. The adhesive layer completely covers the display area, and an edge of the adhesive layer forms a avoidance area. The escaping area exposes the first bonding surface, and the escaping area is located in the non-display area corresponding to the first angle.

The panel bonding structure provided by the creation embodiment can disperse the stress through the escaping area formed by the edge of the adhesive layer to reduce the edge of the first bonding surface after the display panel and the touch panel are bonded together. The stress generated at the corners is concentrated, thereby preventing the occurrence of brightness unevenness such as mura or ripple.

The above embodiment can be applied to the manufacturing method of the panel bonding structure 1 according to the embodiment of the present invention. The bonding method is suitable for bonding a touch panel 11 and a display panel 12 to each other. Please refer to FIG. 6. FIG. 6 is a flow chart showing the steps of the manufacturing process of the panel bonding structure according to an embodiment of the present invention. First, a display panel 11 is provided. The display panel 11 has a first bonding surface S1. The first bonding surface S1 includes a display area A1 and a non-display area A2. The non-display area A2 surrounds the display area A1. A first angle exists between two adjacent edges of the first bonding surface S1 (step S601). Next, a touch panel 12 is provided. The touch panel 12 has a second bonding surface S4, and the second bonding surface S4 faces the first bonding surface S1 of the display panel 11 (step S602). Finally, an adhesive layer 13 is disposed between the first bonding surface S1 and the second bonding surface S4, so that the adhesive layer 13 is adhered between the touch panel 12 and the display panel 11, and the adhesive layer 13 completely covering the display area A1, wherein the edge of the adhesive layer 13 forms a escaping area, the escaping area exposes the first bonding surface S1, and the escaping area is located in the non-display area corresponding to the first angle A2 (step S603).

In summary, the panel bonding structure 1 of the present embodiment can disperse the stress through the escaping areas A301 to A304 formed by the edges of the adhesive layer 13 to reduce the adhesion between the display panel 11 and the touch panel 12. After the first clip of the edge of the first bonding surface S1 The stress generated at the corners G1 to G4 is concentrated, thereby preventing the occurrence of uneven brightness such as mura or ripple, and preventing deformation of the displayed image. In addition, in the embodiment of the present invention, the panel bonding structure 1 can also pass through the avoidance areas A301 ′ to A304 ′ formed by the edges of the adhesive layer 13 to reduce the adhesion between the display panel 11 and the touch panel 12 . The stress generated at the second angle G5 to G8 of the edge of the second bonding surface S4 is concentrated.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of patent protection of the present invention. Anyone who is familiar with the art of the artist, within the spirit and scope of the creation, the equivalent of the change and retouching is still within the scope of the patent protection of the creation.
