Abstract:
Provided is an organic EL display device including an array of pixel circuits 10 each having: organic EL element 32; storage capacity 33 that holds a voltage corresponding to an image signal; drive transistor 34 that applies a current corresponding to the voltage of storage capacity 33 to the organic EL element 32; and current switch 35 that either connects or disconnects the drive transistor 34 with the organic EL element 32. The organic EL display device also includes an inter-pixel switch 15 that connects or disconnects a node between organic EL element 32(p, j) and current switch 35(p, j) in one pixel circuit 10(p, j) out of the pair of the pixel circuits 10 that are adjacent to each other, and a node between organic EL element 32(p+1, j) and current switch 35(p+1, j) in the other pixel circuit 10(p+1, j) out of the pair of the pixel circuits 10.
