Problems solved by technology

In this structure, there is a problem that the wavelength conversion layer is deteriorated, and the luminance and uniformity are reduced due to the characteristics of the micro light emitting device as a point light source
Especially, due to these disadvantages, it is difficult to apply to digital signage displays, flexible displays, etc.

Abstract

The present invention relates to a display device, and more particularly, to a display device using a semiconductor light-emitting diode. The display device according to the present invention comprises: a substrate having a wiring electrode formed thereon; a plurality of semiconductor light-emitting diodes electrically connected to the wiring electrode; an insulating layer provided to fill space between the semiconductor light-emitting diodes; a polarizing filter layer which is overlapped on the insulating layer and filters light incident into a specific direction; and a wavelength conversionlayer which is overlapped on the polarizing filter layer and provided to convert the wavelength of light.

Description

technical field [0001] The present disclosure relates to a display device and a method of manufacturing the same, and more particularly, to a display device using a semiconductor light emitting diode. Background technique [0002] In recent years, display devices having excellent characteristics such as low profile, flexibility, etc. have been developed in the field of display technology. In contrast, currently commercialized main displays are represented by liquid crystal displays (LCDs) and active matrix organic light emitting diodes (AMOLEDs). However, there are problems such as not so fast response time, difficulty in achieving flexibility in case of LCD, and disadvantages such as short lifetime, not so good yield, and low flexibility in case of AMOLED. [0003] On the other hand, light-emitting diodes (LEDs) are well-known light-emitting devices for converting electric current into light, and have been used as light sources for displaying images in electronic devices i...
