Abstract

The invention discloses a display panel and a display device, a binding layer is arranged between a thin film transistor layer and a substrate, and a metal wire of the thin film transistor layer is electrically connected with a binding lead through a via hole, so that the range of a peripheral area can be reduced, narrow bonding can be realized, and the purpose of reducing a frame is realized.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] figure 1 Schematic diagram of the structure of the existing display device. Such as figure 1 As shown, in the existing display device, it is necessary to use the upper glass substrate 10 and the lower glass substrate 20, wherein the TFT layer 30 is provided on the upper surface of the upper glass substrate 10, and the Fanout circuit 40 is made on the lower surface of the lower glass substrate 10, so it needs to pass The side printed circuit 50 connects the TFT layer 30 with the Fanout line 40; at the same time, the chip-on-film 60 and the printed circuit board 70 are connected through the back bonding technology. [0003] However, in the above-mentioned display device, the protection of the side printed circuit 50 and the double-sided circuit is required, the manufacturing process is complicated, the ...
