Abstract
An electroluminescence display comprises transistor arrays, OLEDs, and power source lines. The transistor arrays are arranged in a first direction and a second direction intersecting the first direction. The OLEDs are electrically connected to the transistor arrays, and emit first, second and third colors. The power source lines apply power source voltage to the transistor arrays. The transistor arrays are disposed adjacently in the first direction to share one power source line positioned between the transistor arrays, and include a transistor array of an A type and a transistor array of a B type symmetrical to each other with respect to a reference line extended in the second direction. All the OLEDs emitting a light of any one of the first to third colors are connected to the transistor array of the A type. All the OLEDs emitting another of the first to third colors are connected to the transistor array of the B type.
