摘要:
An EL display apparatus according to the present invention includes EL device (15) adapted to emit light at a luminance corresponding to a current fed thereto. A source driver (14) outputs a current higher than a current corresponding to an image signal to the EL device (15) through a source signal line (18). This operation charges/discharges a parasitic capacitance present in the source signal line (18). A transistor (11d) formed between the EL device (15) and the source driver (14) operates so that the EL device (15) is fed with the current for only a part of a one-frame period. As a result, the El device (15) emits light for only the part of the period.
