Abstract: A circuit for generating drive signals (SHR, SHG and SHB) from an input image signal (SIN), a cell array (1) including a light emitting element (EL) for emitting light of a predetermined color of red (R), green (G) or blue (B) by being applied with a drive signal (SHR, SHG and SHB) supplied for each color from the circuit (2), an adjustment information retrieve means (4) for obtaining information relating light emission adjustment of the light emitting element (EL), and a level adjustment circuit (2B) provided in the circuit (2) for changing a level of an RGB signal (S22) before divided to drive signals (SHR, SHG and SHB) for the respective RGB colors based on the information obtained by the adjustment information retrieve means (4) are provided. In the present invention, color balance adjustment can be performed by the above small scale circuit.
