Title:
画素回路及び表示装置
Document Type and Number:
Japanese Patent JP5346379
Kind Code:
B2
Abstract:
A display device which achieves low power consumption without causing an aperture ratio to be lowered is provided. A pixel circuit (2) includes: an internal node (N1) which holds a voltage of the pixel data supplied to a display element part (21); a first switch circuit (22) which transfers the voltage of the pixel data supplied from a data signal line (SL) to the internal node (N1) through at least a switch element (T4); a second switch circuit (23) which transfers a voltage supplied to a predetermined voltage supply line (VSL) to the internal node (N1) without going through the switch element (T4); and a control circuit (24) which holds a predetermined voltage depending on the voltage of the pixel data held in the internal node (N1), at one end of a first capacitance element (C1) and controls connection/disconnection of the second switch circuit (23).
