Estimating the term…
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 171-1 and 171-2 of a type where a reset operation is periodically necessary, a logic circuit 173 for using a level shift horizontal synchronization signal Hsync to input reset pulses for the MCK level shifters 171-1 and 171-2 having a period of N horizontal periods shifted in phase by M horizontal periods (note, M<N) to the level shifters 171-1 and 171-2 and outputting the resultant signals, and a function of selecting the circuit not performing the reset operation among outputs of the L number of level shifters 171-1 and 171-2 for each M horizontal periods and outputting a level shift master clock LSMCK as a last output signal.
An integral drive circuit type display device supplied with at least a master clock, comprising a level conversion circuit for converting a first level at the time of input of said master clock to a second level of an internal drive voltage level and outputting the same to a predetermined circuit, wherein
An electronic apparatus having an integral drive circuit type display device supplied with at least a master clock,
