Abstract

The present invention relates to a display device using a semiconductor light emitting element and a method for manufacturing the same, and more particularly, to a display device using a semiconductor light emitting element having a size of several [mu] m to dozens of [mu] m and a method for manufacturing the same. The present invention provides a display device, which is characterized by comprising: a base part; a plurality of transistors disposed on the base part; a plurality of semiconductor light-emitting elements disposed on the base part; a plurality of wiring electrodes disposed on the base part and electrically connected to the plurality of transistors and the semiconductor light emitting element; a partition wall disposed on the base part and formed so as to cover the plurality of transistors; and a connection electrode connecting a portion of the plurality of transistors and a part of the plurality of wiring electrodes, the connection electrode being formed so as to penetrate the partition wall.

Description

technical field [0001] The present invention relates to a display device and a manufacturing method thereof, and in particular, to a display device using a semiconductor light emitting element with a size of several μm to several tens of μm and a manufacturing method thereof. Background technique [0002] In recent years, liquid crystal displays (LCDs), organic light-emitting element (OLED) displays, and micro LED (light-emitting diode) displays have been competing to realize large-area displays in the technical field of displays. [0003] On the other hand, if a semiconductor light-emitting element (micro LED (uLED)) having a diameter or cross-sectional area of ​​100 micrometers or less is used in a display, since light is not absorbed by a polarizer or the like in the display, very high efficiency can be provided. . However, millions of semiconductor light-emitting elements are required in large displays, and thus have the disadvantage of being difficult to transfer eleme...
