Abstract

The invention provides a display device, comprising: a display panel comprising a display area and a non-display area, the non-display area comprising a first fan-out area, a second fan-out area and a bending area located between the first fan-out area and the second fan-out area; an optical function film layer formed in the display area and the first fan-out area of the display panel; a bonding layer formed on the optical function film layer; and a protection layer formed on the display panel, wherein the protection layer is located in the bending area and stretches across part of the first fan-out area and part of the second fan-out area; a gap is formed between the optical function film layer and the protection layer; one end, close to the bending area, of the bonding layer exceeds the optical function film layer and is connected with the protection layer, and the bonding layer covers the optical function film layer, the gap and part of the protection layer. The display device provided by the invention not only can play a role in ESD protection, but also can avoid dislocation interference.

Description

technical field [0001] The present application relates to the technical field of flexible display, in particular to a display device. Background technique [0002] With the development and maturity of flexible organic light-emitting device (Organic Light-Emitting Diode, OLED) display technology, borderless OLED display has become one of the important development trends at present. In the manufacturing process of the borderless OLED display, pad bending (Pad Bending) technology becomes one of the keys to determine the yield. [0003] At present, the Pad Bending technology has gradually replaced the COF Bending technology and has become the mainstream Bending technology because it can significantly shorten the frame width of the display panel. The Pad Bending technology needs to cut the display substrate in a special shape, remove the test area of ​​the display substrate, and bend the Pad area to the back of the display substrate to reduce the width of the frame. [0004] In...
