The present invention relates to a display device and, particularly, to a display device using a semiconductor light-emitting element. The display device according to the present invention comprises:a substrate having a wiring electrode; a plurality of semiconductor light-emitting elements electrically connected to the wiring electrode; a plurality of fluorescent substance layers for converting awavelength of light; a wavelength conversion layer having a plurality of partitioning parts formed between the plurality of fluorescent substance layers, and disposed so as to cover the plurality ofsemiconductor light-emitting elements; and a color filter disposed so as to cover the wavelength conversion layer, wherein at least one of the plurality of fluorescent substance layers has a pluralityof layers.

Description

technical field [0001] The present disclosure relates to display devices, and more particularly, to display devices using semiconductor light emitting elements. 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 primary displays are represented by liquid crystal displays (LCDs) and active matrix organic light emitting diodes (AMOLEDs). However, there are problems such as poor response time, difficulty in achieving flexibility in the case of LCD, and disadvantages such as short lifetime, poor yield, and low flexibility in the case of AMOLED. [0003] On the other hand, light-emitting diodes (LEDs) are well-known light-emitting elements for converting electric current into light, and have been used since red LEDs using GaAsP compound semiconductors were manufactured on the market together with GaP:N-b...
