Abstract

The embodiment of the invention provides an OLED substrate and a display device, which relate to the technical field of display, and can solve the problem that light emitted from a light emitting layer in the prior organic electroluminescent device is emitted onto an active layer and affects the characteristics of a thin film transistor. The OLED substrate comprises a substrate, a thin film transistor, a first electrode and a light emitting layer sequentially arranged on the substrate; The thin film transistor comprises an active layer; The OLED substrate further includes a light shielding layer disposed between the active layer and the first electrode. A light emit device for preventing that thin film transistor from beingaffected by light emitted from the light emitting layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED substrate and a display device. Background technique [0002] Organic Electro-luminescent Display (OLED) has many advantages such as self-luminescence, low operating voltage, thinness, flexibility and high color saturation, and has been widely used in display, lighting and other fields. [0003] Among them, the manufacturing process of the organic electroluminescent device includes: forming a thin film transistor (ThinFilm Transistor, referred to as TFT) on the substrate, forming an anode, a pixel defining layer, a light emitting layer and a cathode in sequence on the thin film transistor, wherein the anode and The drain of the thin film transistor is electrically connected. [0004] However, part of the light emitted by the light-emitting layer will be incident on the active layer of the thin film transistor after being refracted and reflected by the film layer in the ...
