Classification: CPC G | IPC G

Claim 7:
8. A display device comprising:
a display panel in which a plurality of pixels, each including a light emitting element and a first transistor configured to drive the light emitting element, are disposed, a power line configured to supply a power voltage applied to the first transistor is disposed, a plurality of data lines electrically connected to the plurality of pixels are disposed, and a plurality of scan lines electrically connected to the plurality of pixels are disposed;
a data driving circuit configured to supply a data voltage to the plurality of data lines;
a scan driving circuit configured to output, to the plurality of scan lines, a scan signal for controlling a timing at which the data voltage is input to the plurality of pixels;
a first emission driving circuit configured to output a first emission control signal for switching an electrical connection between the power line and the first transistor to a first emission control line disposed in the display panel; and
a second emission driving circuit configured to output a second emission control signal for switching an electrical connection between the first transistor and the light emitting element to a second emission control line disposed in the display panel,
wherein a time interval exists between a time at which the first emission driving circuit outputs the first emission control signal having a turn-on level to the first emission control line electrically connected to any one pixel among the plurality of pixels, thereby inputting the power voltage to the one pixel and a time at which the second emission driving circuit outputs the second emission control signal having a turn-on level to the second emission control line electrically connected to the one pixel.
