USE - Micro light emitting semiconductor device used for display apparatus (claimed). ADVANTAGE - The semiconductor device has reduced manufacturing cost, increases luminous efficiency. The interlayer separates the color conversion layer from the micro light emitting chip and prevent characteristics of the color conversion layer from being reduced due to light from the micro light emitting chip. The manufacturing method of the micro light emitting semiconductor device is simple and economical.
