Abstract
A current driving device includes a reference current source, a first MISFET connected to the reference current source, a plurality of current distribution MISFETs which constitutes a current mirror together with the first MISFET and distributes a reference current, a current input MISFET connected to the current distribution MISFETs, and a plurality of current supply sections each of which includes MISFETs constituting a current mirror circuit together with the current input MISFET and supplies a driving current for a pixel circuit. With the plurality of current distribution MISFETs provided, change in gate the potential of MISFETs in the current supply section can be suppressed, so that the generation of a crosstalk in a display device can be suppressed.
