CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0147644 filed in the Korean Intellectual Property Office on Nov. 18, 2019, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present invention relates to a display device, and more particularly, to a display device having a heat dissipation effect.

DISCUSSION OF THE RELATED ART

Display devices typically include a liquid crystal display (LCD), a plasma display panel (PDP), an organic light emitting diode (OLED) device, a field effect display (FED), an electrophoretic display device, or the like.

The light emitting diode device typically includes two electrodes and an emitting layer located therebetween, and excitons are generated by combining, at the emitting layer, electrons provided from one of the two electrodes and holes provided from the other electrode. Energy is outputted from the excitons as they approach a ground state, and thereby emit light.

In the light emitting diode device, a temperature inside the display device increases due to heat generated during a driving of the display device. In this case, as the temperature inside the display device increases, the light emitting layer that is vulnerable to heat may deteriorate. If the light emitting layer deteriorates, a lifespan of the organic light emitting diode device may be shortened and display quality may deteriorate.
