Abstract
A display device is proposed. The device may include a pixel array including n pixel groups, a reference current source including a first reference transistor through which a reference current flows and connected to the pixel array, and n sub-current sources each included in the n pixel groups and each including a first transistor connected to the reference current source, and n pixel circuits connected to the n sub-current sources, respectively. The reference current source may include any one of a second reference transistor and a reference resistor connected to the first reference transistor. Each of the n sub-current sources may provide a first mirroring current, and each of the n pixel circuits may provide a second mirroring current obtained by mirroring the first mirroring current. Each of the n sub-current sources may include any one of an additional transistor and an additional resistor connected to the first transistor.
