Display device
First Claim
1. A display device, comprising:
- a light-emitting unit, comprising;
a light-emitting part, wherein a light extraction structure is disposed on a first surface of the light-emitting part;
a transparent structure disposed on the first surface of the light-emitting part, and comprising;
a first transparent layer adjacent to the first surface of the light-emitting part; and
a second transparent layer disposed on the first transparent layer, wherein a refractive index of the light-emitting part is greater than a refractive index of the first transparent layer, and the refractive index of the first transparent layer is greater than a refractive index of the second transparent layer;
a connective part disposed on a second surface of the light-emitting part, wherein the second surface is opposite to the first surface of the light-emitting part, the connective part comprises a bonding layer, the bonding layer has a first material layer and a second material layer, and a surface of the second material layer disposed adjacent to the first material layer and comprising a concave-convex structure;
a protective part surrounding the light-emitting part and the connective part; and
a substrate having a plurality of active elements and at least one bonding pad, wherein the at least one bonding pad is electrically connected to the connective part of the light-emitting unit;
wherein a roughness of the light extraction structure is greater than or equal to 0.2 μ
m and less than or equal to 5 μ
m.

Abstract
A display device is provided. The display device includes a light-emitting unit. The light-emitting unit includes a light-emitting part, wherein a light extraction structure is disposed on a first surface of the light-emitting part. The light-emitting unit also includes a connective part disposed on a second surface opposite to the first surface of the light-emitting part. The light-emitting unit further includes a protective part surrounding the light-emitting part and the connective part. In addition, the display device includes a substrate having a plurality of active elements and at least one bonding pad, wherein the bonding pad is electrically connected to the corresponding connective part of the light-emitting unit. The roughness of the light extraction structure is greater than or equal to 0.2 μm and less than or equal to 5 μm.
