Patent ID: 8482550

Claim:
A display device, comprising: a plurality of pixel circuits; a power source line connected to corresponding ones of the plurality of pixel circuits; and an output buffer circuit including: a first power source supply terminal connected through a first current path to the power source line such that a first potential appearing on the first power source supply terminal may be selectively applied as a corresponding output potential to the power source line; a second power source supply terminal connected through a second current path to the power source line such that a second potential appearing on the second power source supply terminal may be selectively applied as a corresponding output potential to the power source line; and a variable resistance circuit interposed in the first current path between the first power source supply terminal and the power source line, wherein: the output buffer circuit is configured to supply currents to the corresponding ones of the plurality of pixel circuits by applying a selected corresponding output potential corresponding to either the first potential or the second potential to the power source line; the variable resistance circuit is configured such that a resistance value thereof changes smoothly based on a magnitude of a total sum of the currents supplied to the corresponding ones of the plurality of pixel circuits; and the variable resistance circuit suppresses a change in the selected corresponding output potential when the magnitude of the total sum of the currents supplied to the corresponding ones of the plurality of pixel circuits changes.
