Abstract

The invention discloses a display panel and a display device in order to better protect a metal wire connecting area in the peripheral wire area, improve protection strength and prevent a wire from being broken. The display panel comprises a grid insulation layer arranged on a grid metal layer, a protective layer, a passivation layer and an ITO covering layer, wherein the protective layer, the passivation layer and the ITO covering layer are sequentially arranged on the grid insulation layer. By means of the display panel and the display device, the thickness of a film layer in the peripheral wire area can be increased, and therefore the whole peripheral wire area especially the metal connecting wire area exposed outside a color film panel can be protected, and protection strength is improved.

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] With the continuous development of display technology, thin film transistor liquid crystal display devices are more and more widely used. [0003] The display panel of the existing thin film transistor liquid crystal display device has a peripheral wiring area formed by passing the signal line inside the display panel through the via hole transfer technology, including the peripheral wiring area on the signal line side and the peripheral wiring area on the gate line side, wherein, The peripheral routing area on the signal line side is made of the data metal layer (SD metal layer) that makes the source electrode and drain electrode of the thin film transistor. The gate metal layer leads out the gate signal line. [0004] In the production process, in the peripheral wiring area, it is necessary to lead o...
