Abstract

The invention provides a display device and a preparation method thereof. The display device comprises an array substrate, a first pixel definition layer, an organic light-emitting diode, a first flatlayer, a second pixel definition layer and a color film layer. The first pixel definition layer is arranged on the array substrate. The first pixel definition layer comprises a plurality of first through holes; the organic light-emitting diode is arranged in the first through hole so as to be electrically connected with the array substrate; the organic light-emitting diode comprises one of a blueorganic light-emitting diode and an ultraviolet organic light-emitting diode; the first flat layer is arranged on the first pixel definition layer and the organic light-emitting diode; the second pixel definition layer is arranged on the first flat layer, and the second pixel definition layer comprises a plurality of second through holes, a plurality of third through holes and a plurality of fourth through holes; and the color film layer is arranged in the plurality of second through holes, the plurality of third through holes and the plurality of fourth through holes. The display performanceand the service life of the display device are improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and a manufacturing method thereof. Background technique [0002] OLED is an Organic Light-Emitting Diode (Organic Light-Emitting Diode), which has the characteristics of self-illumination, high brightness, wide viewing angle, high contrast, flexibility, and low energy consumption. It began to gradually replace the traditional LCD (Liquid Crystal Display), and is widely used in mobile phone screens, computer monitors, full-color TVs, etc. OLED can be divided into top emission type and bottom emission type according to the light emitting characteristics, and OLED has the characteristics of light and thin. However, the current display devices have the problems of poor display performance and low service life. Contents of the invention [0003] The present application provides a display device and a preparation method thereof, so as to solve the probl...
