An organic electroluminescent device with improved working life and manufacturing method thereof

Abstract

The invention discloses an organic electric light-emitting device, particularly an organic electric light-emitting device that can prolong the service life and its making method, mainly arranging a transparent isolating layer on the top surface of a color filter plate, defining and forming at least a bottom electrode on the transparent isolating layer, then etching to remove the part of the transparent isolating layer uncovered by the bottom electrodes to form a moisture excluding channel so as to dry and exclude the solvent or steam in the color filter plate in the baking course, thus reducing the degrading speed of the organic light-emitting layer and effectively prolonging the service life of the organic electric light-emitting device.

Description

technical field [0001] The invention relates to an organic electroluminescent device, in particular to an organic electroluminescent device with improved service life and a manufacturing method thereof. Background technique [0002] With the vigorous development of the optoelectronic industry, people enjoy the convenience brought by technology. However, how to manufacture high-quality and low-cost flat-panel displays or light-emitting devices has always been a goal that major manufacturers are striving to achieve. Among many displays and light-emitting devices, compared with other light-emitting devices, organic electroluminescent devices (OLEDs) have the advantages of self-luminescence, high brightness, wide viewing angle, low power consumption, high response speed, light and thin panels, and component structures and It is easy to make and other advantages, so it has attracted the attention of research institutes and manufacturers in various countries. [0003] For variou...

Problems solved by technology

[0009] Although the water vapor or solvent remaining inside the color filter 11 can be removed by the above method, however, since the light-transmitting isolation layer 111 is not conducive to allowing water vapor or solvent to pass through during the baking process, the color filter 11 The effect and efficiency of drainage treatment cannot be demonstrated, and the service life of the organic light-emitting device 10 cannot be effectively improved.
