Abstract
A drive circuit array substrate allowing for tests without mounting any driver ICs and without using expensive panel contact jigs and production and test methods thereof are provided. A data voltage application circuit, data selection circuit, gate selection circuit, and anode driver connected to a display pixel forming zone are formed on a drive circuit array substrate. The data voltage application circuit, data selection circuit, gate selection circuit, and anode driver allows for lighting test and aging test of the light emitting elements in the display pixel forming zone and measurement of transistor characteristics without mounting any driver ICs and without using expensive panel contract jigs.
