Document Type and Number:
Japanese Patent JP5249325
Kind Code:
B2
Abstract:
A display device includes luminescence pixels that each include a driving transistor, a luminescence element, and a switching transistor that switches between conduction and non-conduction between a data line and an anode or a cathode of the luminescence element. A data driving circuit supplies a signal voltage to the data line, and a bias supplying circuit supplies a predetermined bias voltage to the data line. A controller applies the predetermined bias voltage to the anode or the cathode of the luminescence element by causing a non-conduction state between the data line and the data driving circuit, causing a conduction state between the data line and the bias supplying circuit, and switching the switching transistor ON within a period in which a signal current does not flow to the luminescence element.
