Display substrate and display device

Abstract

The embodiment of the invention provides a display substrate and a display device and relates to the technical field of organic electroluminescence displayers. The display substrate solves the problem that in the prior art, electrical property drift is generated due to changes of the threshold voltage in a thin film transistor when an organic electroluminescence displayer is manufactured, avoids the influence on electrical properties of the thin film transistor, improves the stability of performance of products and reduces production cost. The display substrate comprises the thin film transistor and is characterized by further comprising a grounding circuit, wherein one end of the grounding circuit is connected to the thin film transistor, and the other end of the grounding circuit is grounded; the grounding circuit and a conducting layer structure of the thin film transistor are formed simultaneously in the process of manufacturing the thin film transistor. The display substrate and the display device are applied to manufacturing of the organic electroluminescence displayers.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescent displays, in particular to a display substrate and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) has the advantages of active luminescence, all solid state, low driving voltage, high efficiency, fast response, wide viewing angle, simple manufacturing process, and large-area and flexible display. It has broad application prospects in lighting and lighting, and has attracted strong attention from academia and industry since its birth. After continuous development of technology, small-sized active matrix organic light-emitting diode (Active Matrix / Organic Light Emitting Diode, referred to as AMOLED) display has been first applied in high-end mobile phones and tablet computers; in large-sized applications, Samsung Electronics, etc. The company launched a 55-inch AMOLED TV, and even introduced a curved AMOLED TV for better visual effects.
