Abstract

The invention discloses a display panel and a display device.The display panel comprises an array substrate and a light-emitting device, and the light-emitting device is located in a light-transmitting area of the array substrate and comprises a first transparent electrode, an organic light-emitting layer and a second transparent electrode which are sequentially stacked on the array substrate; and in the array substrate, a thin film transistor and a second storage capacitor are located in a non-light-transmitting area, and the first storage capacitor is located in the light-transmitting area. According to the display panel and the display device adopting the display panel, the technical problem that in the prior art, a bottom emission light-emitting device and a top emission light-emitting device cannot achieve double-sided display or transparent display can be solved.

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] At present, in the field of OLED display, OLED light-emitting devices usually have two structures: bottom emission and top emission. [0003] figure 1 is a schematic diagram of an existing bottom emission structure display panel, figure 2 A schematic diagram of a display panel for an existing top-emitting structure. Such as figure 1 with figure 2 As shown, the bottom emission anode 11 is usually made of ITO, the cathode 12 is usually made of Al; the top emission anode 21 is usually made of ITO / Ag / ITO, and the cathode 22 is usually made of IZO / Ag / IZO or Mg / Ag . Obviously, the above two emission structures can only achieve single-sided display, but cannot achieve double-sided display or transparent display. Therefore, the display devices with the above two emission structures cannot meet the scena...
