摘要:
A light-emission control switch transistor and a threshold compensation switch transistor are transistors having different conductivity types. Gate potentials at the light-emission control switch transistor and the threshold compensation switch transistor are controlled using a first control signal. A gate potential at the data signal switch transistor is controlled using a second control signal. A control circuit selects rows sequentially. in a selected one of the rows, the light-emission control switch transistor is maintained off, the threshold compensation switch transistor is maintained on, and the data signal switch transistor is maintained off in a first period. In the selected row, the light-emission control switch transistor is maintained on, the threshold compensation switch transistor is maintained off, and the data signal switch transistor is maintained on in a second period after the first period.
