Abstract

Embodiments of the present invention provide a display substrate and a display device, which relate to the technical field of organic electroluminescent displays, and solve the problem that the threshold voltage of thin-film transistors in the prior art will change when making organic electroluminescent displays, resulting in electrical problems. The problem of drift avoids the influence on the electrical properties of the thin film transistor, improves the stability of the performance of the product, and reduces the production cost. The display substrate includes a thin film transistor, and it is characterized in that the display substrate further includes: a grounding line, wherein: one end of the grounding line is connected to the thin film transistor, and the other end of the grounding line is grounded; wherein, The grounding line is formed simultaneously with the conductive layer structure of the thin film transistor during the process of forming the thin film transistor. The invention is applied in the manufacture of organic electroluminescent displays.

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 (ActiveMatrix / 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 and other companies A 55-inch AMOLED TV was introduced, and even a curved AMOLED TV was introduced for better visual effe...
