Abstract

The invention describes a display device and a fabrication method thereof. The display device comprises a substrate, a driving circuit layer, a light-emitting device layer, a thin film package layer,a touch sensing unit and a protection layer, wherein the driving circuit layer comprises a pin, the pin is arranged at a non-display region, the thin film package layer comprises a first inorganic package layer, the touch sensing unit comprises a touch insulation layer, the projection edges of the first inorganic package layer and the protection layer on the substrate are coincided, or the projection profiles of the first inorganic package layer and the touch insulation layer on the substrate are same, and the projections of the first inorganic package layer and the protection layer / the touchinsulation layer on the substrate does not cover the pin. During the pattering process, the first inorganic package layer and the protection layer / the touch insulation layer employs the same mask, themask and the etching process are saved, the production efficiency is greatly improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the display field, in particular to a display device and a manufacturing method thereof. Background technique [0002] Since the emergence of display technology, technology has developed very rapidly. Cathode ray tube technology (CRT), plasma display technology (PDP), liquid crystal display technology (LCD), and the latest organic light-emitting display technology (OLED), micro-diode technology have appeared successively. Display technology (micro LED). [0003] With the development of society and the continuous improvement of human needs for material life, today's display technology is moving towards narrow borders, high contrast, high resolution, full-color display, low power consumption, high reliability, high integration, and long life. And the direction of thin and light is advancing rapidly, and the research on flexible display (soft screen) technology is also constantly improving and deepening. Different from tradition...
