Abstract:
1. An active matrix type display apparatus, comprising: display elements operated in response to a driving current; driver transistors for supplying the driving current to said display elements in accordance with input signals; capacitors each connected to gate electrodes of said driver transistors for storing potential differences between source and gate electrodes of said driver transistors; switches connected between the gate and drain electrodes of said driver transistors; scanning lines connected to said switches; a scanning line driver circuit; and buffer circuits connected between said scanning line driver circuit and said scanning lines to supply the scanning signals to said switches, wherein said buffer circuits are configured to make transient time of waveforms at output terminals of said buffer circuits from one state of the scanning signals to another state substantially the same as that at end terminals of said scanning lines when said switches shifts from its turned-on state to its turned-off state.
