Abstract

The present invention provides a display panel and a display device. The display panel includes a stacked substrate, a light emitting layer, a packaging layer and a light shielding unit. The light emitting layer includes a plurality of light emitting units for emitting light of different colors. In the direction of the substrate, the projection of part of the shading unit overlaps with the projection of part of the light emitting unit; a protruding structure or a concave structure is provided on the light output path of the display panel, and the refraction of the protruding structure or the concave structure The index is greater than the refractive index of the encapsulation layer. The invention further improves the display effect of the display panel.

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] An organic light-emitting diode (Organic Light-Emitting Diode; OLED) is a current-injection light-emitting display device, which consists of an anode, an organic light-emitting layer and a cathode in a sandwich structure. After electrification, the hole on the anode and the charge of the cathode combine in the organic light-emitting layer and release energy, which makes the organic light-emitting substance molecules in the organic light-emitting layer transition from the ground state to the excited state. The excited state is very unstable, and the excited molecules return to the ground state from the excited state, and luminescence occurs in the process of radiative transition. The OLED display device includes a metal layer, and the metal layer has a high reflectivity to external ambient light, and the...
