Abstract:
1. A display device comprising: a plurality of pixels; and a drive circuit which drives the plurality of pixels, wherein the drive circuit includes: a first transistor which has a first electrode thereof connected to a power source line to which a reference voltage V1 is applied; and a second transistor which has a first electrode thereof connected to a second electrode of the first transistor and allows a bias voltage Vc to be applied to a control electrode thereof, wherein when the first transistor assumes an OFF state, assuming a voltage applied to a second electrode of the second transistor as V2, a relationship V2<Vc<V1 is satisfied, and wherein the relationship 0.9×(V1−V2)/2≦Vc≦1.1×(V1−V2)/2 is established.
