The present application is applicable to the field of display technology, and provides a display panel and a
display device. The display panel includes a first substrate, a second substrate and a packaging
adhesive layer. The first substrate includes a display area and a frame area. A plurality of pixels are arranged in the display area, and an
electrode circuit is arranged in the frame area. The packaging
adhesive layer is arranged in the frame area and is located between the
electrode circuit and the second substrate. An optical structure is arranged on the second substrate, which can reflect or refract the light inside and / or outside the packaging
adhesive layer to the contact interface between the packaging adhesive layer and the second substrate. The present application arranges an optical structure on the second substrate, so that the part of the light that originally cannot directly reach the packaging adhesive
powder can change the propagation direction, reach the contact interface between the packaging adhesive
powder and the second substrate, and be utilized, thereby increasing the
laser energy at the upper end of the packaging adhesive
powder, improving the
bonding strength between the upper end of the packaging adhesive layer and the lower surface of the second substrate, and ensuring a good packaging effect between the packaging adhesive layer and the second substrate.
