Abstract
A display apparatus is provided with a current driving type light-emitting device and a driving device for controlling a driving current flowing through the light-emitting device for each pixel of the display apparatus. The display apparatus consists of power source units for supplying power for causing a driving current to flow via the driving device to the light-emitting device via a power source wire, and signal wire driving units for supplying a data signal to the driving device via signal wires. In addition, voltage adjusting units adjust a voltage for the power source units or a data signal from the signal wire driving units so that a quantity of a driving current flowing through the light emitting device when a data signal of a predetermined voltage is supplied to the driving device via signal wires or a quantity of emitted light emitted from the light-emitting device comes close to a predetermined reference value.
