Abstract
Provided is a display device. The display device includes a substrate having a sub-pixel area. In some examples, the substrate may have or define a plurality of sub-pixel areas. A light-emitting diode (LED) and a thin-film transistor for driving the LED are disposed in the sub-pixel area. An extended light path layer is disposed on the substrate and is configured to surround the sub-pixel area. Accordingly, it is possible so as to improve the luminous efficiency of the display device.
