Abstract

An active matrix display device includes a driving section provided on a substrate, an insulating film stacked on the substrate, and light-emitting elements arranged in a matrix on the insulating film, and each of the light-emitting elements includes an light-emitting layer between its upper and lower electrodes, the active matrix display device being driven by the driving section provided for each of the light-emitting elements, the active matrix display device also including a first wiring required to cause the light-emitting element to emit light, and a second wiring disposed in the underlying layer of the first wiring via the insulating film, the second wiring also required to cause the light-emitting element to emit light, wherein the first or second wiring is branched into a plurality of wirings at the intersection between the two wirings.

Description

technical field [0001] The invention relates to an active-matrix display device having light-emitting elements arranged in a matrix, which are driven by drive means provided for each light-emitting element. More specifically, the present invention relates to techniques for improving the yield of active matrix display devices. Background technique [0002] An organic EL display device using an organic electroluminescence element (hereinafter referred to as an organic EL element) is known as a self-luminous active matrix display device. That is, the organic EL display has organic EL elements arranged in a matrix and a driving device for each organic EL element. The organic EL element is a current light-emitting element, and has an organic substance layer between its anode and cathode electrodes. The organic material layer includes a hole transport layer and a light emitting layer stacked one by one. The light emitting layer includes organic substances. Therefore, the organ...
