Abstract: A display device includes a plurality of pixels arranged in a first direction; a first data line extending along a first edge of the pixel row; a second data line extending along a second edge of the pixel row; a first pixel connected to the first data line; and a second pixel adjacent to the first pixel and connected to the second data line. Each of the first and second pixels includes a light emitting diode, a first transistor to transmit a driving current to the light emitting diode, a second transistor to transmit a data signal to the first transistor, a third transistor to transmit the data signal having a compensated threshold voltage to the first transistor, and a fourth transistor to transmit an initialization voltage signal to the first transistor. The first and second transistors are PMOS transistors. The third and fourth transistors are NMOS transistors.
