An active matrix type organic EL display apparatus according to the
present invention which apparatus uses current writing type pixel
circuits is provided with a current control circuit for each of data
lines connected to the pixel circuits. The current control circuit
supplies part of a data line current to a pixel circuit as a bypass
current. The current control circuit handles the bypass current of the
data line current represented by (data line current=data current+bypass
current). Thereby, the data line driving current can be set greater than
the data current flowing through TFTs provided in the pixel circuit, thus
reducing luminance data writing time. Also, when the writing time is set
unchanged, transistor size of the TFTs provided in the pixel circuit can
be reduced.
