Abstract

According to the display device and the preparation method thereof, the first light-emitting layer comprises the light-emitting materials of the first color and the second color, the first light-emitting layer comprising the light-emitting materials of the two colors can be formed by adopting one mask in an evaporation mode, the number of used masks is reduced, therefore, the technological process is simplified, and the preparation cost is reduced. The first color micro-cavity adjusting layer is located on any side of the first light-emitting layer, the second color micro-cavity adjusting layer is located on any side of the first light-emitting layer, and the thickness of the first color micro-cavity adjusting layer is larger than that of the second color micro-cavity adjusting layer; the first color microcavity adjusting layer and the second color microcavity adjusting layer are formed at positions corresponding to the first light emitting layer. The first color micro-cavity adjusting layer is used for extracting the light color of the first color, and the second color micro-cavity adjusting layer is used for extracting the light color of the second color, so that single light colors can be respectively extracted without arranging a color filter, the efficiency is improved, the light loss is reduced, and the service life of the display device is prolonged.

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] With the continuous development of display technology, researchers have developed a variety of display devices, among which OLED (Organic Light-Emitting Diode, organic light-emitting diode) display devices can realize flexible display and bright colors because of their self-luminescence. And other characteristics, and become a hot field for the development of the display industry. [0003] At present, in the process of manufacturing an OLED display device, multiple masks need to be used to form the OLED display device, the process flow is complicated, the manufacturing difficulty of the device is increased, and the manufacturing cost is relatively high. Contents of the invention [0004] In view of this, the object of the present application is to provide a display device and a manufa...
