Patent ID: 7274625

Claim:
A display device comprising: a display panel having a plurality of pixels; and a driver circuit that drives the plurality of pixels, respectively, wherein the driver circuit includes an oscillator circuit, wherein the oscillator circuit includes: (2n+1) inverters having a first inverter to a (2n+1)-th inverter which are connected in series when n is an integer of 1 or larger; an integrator circuit having an input terminal connected to an output terminal of the (2n+1)-th inverter and an output terminal connected to an input terminal of the first inverter; first and second p-type transistors which are connected in series between the input terminal of the first inverter and a first reference potential; and first and second n-type transistors which are connected in series between the input terminal of the first inverter and a second reference potential, wherein an output voltage of a j-th inverter is applied to control electrodes of the first p-type transistor and the first n-type transistor, wherein an output voltage of a k-th inverter is applied to control electrodes of the second p-type transistor and the second n-type transistor, and wherein j is an odd number, and k is an even number, and j<k=2n is satisfied.
