Claim:
1. A light sensitive circuit comprising: a light sensitive capacitor configured to change its charge storing characteristics in response to received light of a predetermined one or more wavelengths; a driving transistor including a gate electrode electrically connected to the light sensitive capacitor; and a first switching transistor configured to be driven in response to an (n+1)-th (n is a natural number) gate signal which is activated in succession after activation of an n-th gate signal and to transfer a driving reference voltage to the gate electrode in the driving transistor, the driving reference voltage being a predetermined reference voltage, the n-th and (n+1)-th gate signals being signals generated by drive circuitry of the display panel, wherein the first switching transistor is a photo transistor that is responsive to a predetermined one or more wavelengths of light, and wherein the first switching transistor is directly connected to the driving transistor.
