Abstract

A display device includes a display panel having a data display area in which pixels are arranged and a lighting part outside the data display area; a display panel driver driving an organic light-emitting diodes in the pixels; and a lighting driver driving an organic light-emitting diodes in the lighting part; and a power supply part generating the high-potential power supply voltage and the low-potential power supply voltage, wherein the lighting part includes: one or more second high-potential power supply lines connected between the power supply part and the organic light-emitting diodes in the lighting part; and a switch connected to the second high-potential power supply lines, and wherein the lighting driver turns on the switch to supply the high-potential power supply voltage to the organic light-emitting diodes in the lighting part when there is an user input or a system power is turned off.
