Abstract

The invention discloses an organic light-emitting display panel and a manufacturing method of the organic light-emitting display panel. The organic light-emitting display panel comprises an upper substrate, a first electrode layer, an organic light-emitting layer, a second electrode layer and a lower substrate, which are sequentially arranged, wherein a refraction layer is arranged on one side, deviating from the organic light-emitting layer, of the first electrode layer and comprises a plurality of convex bodies; each convex body is provided with a sharp corner, and the sharp corner faces the side deviating from the organic light-emitting layer. According to the technical scheme, through the refraction layer with the convex bodies, light emitted by the organic light-emitting layer can be effectively converged, and parallel light is formed within scope of each view angle, so that color offset of view angles is reduced.

Description

technical field [0001] The invention relates to display device structure technology, in particular to an organic light-emitting display panel and a manufacturing method thereof. Background technique [0002] An active-matrix organic light-emitting diode (Active-Matrix Organic Light-Emitting Diode, AMOLED for short) display panel is a common display device at present, and may be referred to as an organic light-emitting display panel for short. [0003] The typical structure of the existing organic light-emitting display panel is as follows: figure 1 As shown, its main structure includes an upper substrate 101 , a first electrode layer 102 , an organic light emitting layer 103 , a second electrode layer 104 and a lower substrate 105 . There may be other structures such as packaging shells on the outer side of the upper substrate 101 . The first electrode layer 102 and the second electrode layer 104, which can also be referred to as the cathode layer and the anode layer, form...
