Abstract
A display device able to amplify the same input as a power supply voltage of IC by using low temperature polysilicon having high threshold voltage and large variation and an electronic apparatus using the same, including MCK use level shifters-and-of a type where a reset operation is periodically necessary, a logic circuitfor using a level shift horizontal synchronization signal Hsync to input reset pulses for the MCK level shifters-and-having a period ofhorizontal periods shifted in phase byhorizontal periods (note, M<N) to the level shifters-and-and outputting the resultant signals, and a function of selecting the circuit not performing the reset operation among outputs of thenumber of level shifters-and-for each M horizontal periods and outputting a level shift master clock LSMCK as a last output signal.
