Problems solved by technology

However, the current solution has the following two disadvantages: (1) since the organic light-emitting device 1 emits light from the top surface, the auxiliary electrode 15 disposed on the top surface will reduce the aperture ratio of the pixel; (2) since the auxiliary electrode 15 uses A mask (mask) is deposited on the second electrode 14. In order to manufacture a high-resolution organic light-emitting device 1, the size of the auxiliary electrode 15 must be relatively reduced. Dimensions are difficult and costly, and if the size of the auxiliary electrode 15 is too thin, the conductivity cannot be effectively increased

Abstract

The invention comprises a baseboard, an auxiliary electrode, an insulation layer, a first electrode, at least one organically-functionalized layer and a second electrode. The part of second electrode is connected to the auxiliary electrode.

Description

technical field [0001] The invention relates to a light-emitting device and an electrode substrate, in particular to an organic light-emitting device and an electrode substrate that emit light from a top surface. Background technique [0002] An organic light-emitting device (Organic Electroluminescent Device) is a device that utilizes the self-luminous properties of organic functional materials (organic functional materials) to achieve display effects. It can be divided into small molecule organic light-emitting devices ( Small molecule OLED (SM-OLED) and polymer light-emitting device (polymer light-emitting device, PLED) two categories. Due to the advantages of self-illumination, no viewing angle, power saving, easy manufacturing process, low cost, high response speed and full color, organic light-emitting devices have great application potential and are expected to become the next generation of flat-panel displays. [0003] Please refer to FIG. 1 , a conventional organic...
