Abstract

The present invention relates to a display apparatus and, particularly, to a display apparatus using a semiconductor light emitting device. A display apparatus according to the present invention comprises: a substrate including a wiring electrode formed therein; a plurality of semiconductor light emitting devices electrically connected to the wiring electrode; a plurality of phosphor layers for converting wavelengths of light; a plurality of partition parts disposed among the plurality of phosphor layers; a wavelength converting layer disposed to cover the plurality of semiconductor light emitting devices; a color filter disposed to cover the wavelength converting layer; and an adhesive layer disposed between the color filter and the wavelength converting layer, wherein at least one of theplurality of partition parts includes metal thin films and a light transmitting material disposed in a space between the metal thin films, and the adhesive layer is formed to fill at least a part ofthe space between the metal thin films.

Description

technical field [0001] The present disclosure relates to a display device and a method of manufacturing the same, and more particularly, to a flexible display device using a semiconductor light emitting device. Background technique [0002] In recent years, display devices having excellent characteristics such as thin profile, flexibility, and the like have been developed in the field of display technology. In contrast, currently commercialized primary displays are represented by liquid crystal displays (LCDs) and active matrix organic light emitting diodes (AMOLEDs). [0003] However, in the case of LCD, there are problems such as not too fast response time, difficulty in achieving flexibility, and in the case of AMOLED, there are disadvantages such as short lifetime, not so good yield, and low flexibility. [0004] On the other hand, a light emitting diode (LED) is a well-known light emitting device for converting electric current into light, and has been used as a light ...
