摘要： In a display device which includes a scanning circuit, an ON resistance of a non-selection switch of the scanning circuit is set larger than an ON resistance of a selection switch. By setting the ON resistance of the non-selection switch of the scanning circuit larger than the ON resistance of the selection switch, an element size of the non selection switch can be made small and hence, a chip size of a scanning driver which is formed of a semiconductor integrated circuit constituting a scanning circuit can be made small without adversely influencing the display characteristics of the display device.

摘要： An increase in the circuit size of a drive circuit that accompanies multi-gradation is reduced. Herein, VI0 to VIM are modulation circuit reference voltages in which a prescribed range, i.e., from a non-emission voltage VEOFF to a maximum emission voltage VEON, is divided in M equal parts. Higher-order dividing resistor (40) equally divides the parts of the modulation circuit reference voltages VI0 to VIM (where VI0>VI1 . . . >VIM−1>VIM) and generates 2J+1 higher-order gradation voltages v0 to v8M (where 8M is equal to 2J) A higher-order decoder unit (41) selects two adjacent voltages from the higher-order gradation voltages in accordance with the data of the higher-order J bits held in the data latch. Complimentary MOSFET selection switches (47-1) and (47-2) open and close in accordance with the lowest-order bit data inputted to the higher-order decoder unit (41). A lower-order dividing resistor (43) equally divides the voltage between the selected high-voltage higher-order gradation voltage vl and the low-voltage higher-order gradation voltage v1+1, and generates 2K gradation voltages vl0 to vln−1 (where n is equal to 2K). A lower-order decoder unit (44) selectively outputs an output voltage from the gradation voltages generated by the dividing resistors in accordance with the data of the lower-order K bits held in the data latch.
