Problems solved by technology

With the investment of a lot of time and money, the size of light-emitting diodes has been reduced year by year. However, it is still difficult to use light-emitting diodes in the pixel structure of light-emitting devices, especially when a single pixel has red sub-pixels, green sub-pixels and In the light-emitting device of the blue sub-pixel, the size of a single sub-pixel is very small, and there is a problem of low process yield no matter when manufacturing a light-emitting diode conforming to a small-sized sub-pixel or when transposing the light-emitting diode. Therefore, A kind of method that can solve the foregoing problems is urgently needed at present

Embodiment Construction

[0048] figure 1 It is an exploded schematic diagram of a light emitting device according to an embodiment of the present invention. figure 2 yes figure 1 Schematic cross-sectional view of section line 11'.

[0049] Please refer to figure 1 and figure 2 , the light emitting device 10 includes a first light emitting element layer 100 , a second light emitting element layer 200 and a third light emitting element layer 300 .

[0050] The first light emitting element layer 100 has a back surface B1 and a light emitting surface F1 opposite to the back surface B1. The first light emitting element layer 100 has a first substrate 110 and a plurality of red light emitting elements R on the first substrate 110 . The red light emitting element R emits directional light, and the light emitted by the red light emitting element R leaves the first light emitting element layer 100 from the light emitting surface F1.

[0051] In this embodiment, the red light emitting element R includes...

Abstract

A light emitting device includes a first light emitting element layer, a second light emitting element layer, and a third light emitting element layer. The first light emitting element layer has a plurality of red light emitting elements. The second light emitting element layer is located on the light emitting surface of the first light emitting element layer and has a plurality of green light emitting elements. The third light emitting element layer is located on the light emitting surface of the second light emitting element layer and has a plurality of blue light emitting elements. The green light emitting element is correspondingly disposed on the red light emitting element. The blue light emitting element is correspondingly disposed on the green light emitting element.

Description

technical field [0001] The present invention relates to a light emitting device, and in particular to a light emitting device comprising a first light emitting element layer, a second light emitting element layer and a third light emitting element layer. Background technique [0002] Light-emitting diode is a kind of electroluminescent semiconductor element, which has the advantages of high efficiency, long life, not easy to break, fast response speed and high reliability. With the investment of a lot of time and money, the size of light-emitting diodes has been reduced year by year. However, it is still difficult to use light-emitting diodes in the pixel structure of light-emitting devices, especially when a single pixel has red sub-pixels, green sub-pixels and In the light-emitting device of the blue sub-pixel, the size of a single sub-pixel is very small, and there is a problem of low process yield no matter when manufacturing a light-emitting diode conforming to a small-...
