Abstract

The present disclosure relates to a display device and a manufacturing method thereof. The manufacturing method of the display device includes the following steps: forming a bonding pad over a dielectric layer. A light-shielding material is formed over the dielectric layer. The temperature of the light-shielding material is raised to cure the light-shielding material into a light-shielding layer.During the process of curing the light-shielding material into the light-shielding layer, the light-shielding material flows to a part of the surface contacting the bonding pad. A light emitting element is electrically connected to the bonding pad.

Description

technical field [0001] The disclosure relates to a display device and a manufacturing method thereof. Background technique [0002] In recent years, light-emitting diodes (light-emitting diodes; LEDs) have been widely used in consumer electronics applications. Light-emitting diodes have many advantages, such as lower energy consumption, longer lifetime, smaller size and faster switching, so they are suitable for use as light sources. In addition, light emitting diodes have also begun to be introduced into display devices. Light emitting diodes in display devices can be driven by thin film transistors or circuit layers. However, in such a structure, part of the elements may cause light leakage in the display device due to reflection of ambient light, resulting in a decrease in display quality. Therefore, how to improve the above problems has become one of the current research and development topics in related fields. Contents of the invention [0003] An embodiment of t...
