Embodiment Construction

[0025] best practice

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In order to fully convey the idea of ​​the present invention to those skilled in the technical field to which the present invention pertains, the embodiments described below are provided as examples. Therefore, the present invention is not limited to the Examples described below, and may be embodied in other forms. In addition, in the drawings, the width, length, thickness, and the like of constituent elements may be exaggerated for convenience. In addition, when it is described that one constituent element is located "on" or "on" another constituent element, not only the case where each part is "directly" on "on" or "on" another part is included, but also the case where each constituent element A situation where another constituent element is interposed between another constituent element. Throughout the specification, the same referen...

Abstract

The light-emitting element for display according to one embodiment includes: a first LED stack that generates light of a first peak wavelength; a second LED stack located below the first LED stack and generating light of a second peak wavelength; a third LED stack located below the second LED stack and generating light of a third peak wavelength; and a floating reflective layer located on the upper portion of the first LED stack layer and reflecting light of the first peak wavelength, where the first peak wavelength is longer than the second peak wavelength and the third peak wavelength.

Description

technical field [0001] The present invention relates to a light-emitting element for display and a display device, in particular to a light-emitting element for display having a stacked structure of a plurality of light-emitting diodes and a display device having the same. Background technique [0002] Light-emitting diodes are used as inorganic light sources in various fields such as display devices, vehicle lamps, and general lighting. Light-emitting diodes are rapidly replacing existing light sources due to their long life, low power consumption, and fast response. [0003] In addition, existing light emitting diodes are mainly used as backlight sources in display devices. Recently, however, LED displays that directly realize images using light emitting diodes are being developed. [0004] Display devices usually utilize mixed colors of blue, green and red to achieve various colors. A display device includes a plurality of pixels to realize various images, and each pix...
