Patent ID: 8274454

Claim:
An Electro Luminescence (EL) display panel having a pixel structure corresponding to an active matrix drive system, comprising: a reverse bias potential generating portion configured to generate a reverse bias potential in which a corresponding one of gradation values of pixels is reflected; and a voltage applying portion configured to apply the reverse bias potential to a gate electrode of a drive transistor composing a pixel circuit adapted to operate for a non-emission time period, wherein the reverse bias potential is given by: Vini=Vthel+Vcat −(α Vsig +β)(α>0 and β≧0) where Vini is the reverse bias potential, Vthel is a threshold potential of an EL light emitting element, Vcat is a cathode potential of said EL light emitting element, α and β are coefficients, and Vsig is a signal potential.
