▎ 摘  要

NOVELTY - The device (10) has a base substrate (101). The pixel electrodes (201) are provided on the base substrate. A common electrode (202) is provided on the pixel electrodes. A light emitting layer is provided between the pixel electrodes and the common electrode. A thin film encapsulation layer (500) is provided on the common electrode. The color filters are provided on the thin film encapsulation layer. The thin film encapsulation layer is included with an inorganic layer (501) and a two-dimensional crystalline material layer (502). The inorganic layer is included with silicon oxide (SiOx), silicon nitride (SiNx), aluminum oxide (Al2O3), halfnium oxide (HfOx), titanium (TiO2), and zirconium oxide (ZrO2). The two-dimensional crystalline material layer is any one of graphene, molybdenum sulfide (MoS2), molybdenum diselenide (MoSe2), tungsten disulfide (WS2), and tungsten diselenide (WSe2). USE - Display device. ADVANTAGE - The thin film encapsulation layer is made of graphene so as to reduce water vapor permeability of the thin film encapulation layer and simplify manufacturing process of the film encapeulation layer, thus reducing manufacturing cost, process time and improving productivity. The thickness of the light-emitting layer can be decreased so that light loss and distortion in the thin-film encapsulation layers can be reduced, thus improving efficiency, resolution and color reproducibility of the device. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the display device.
