Abstract
A method of fabricating a light emitting screen 1 comprises steps of providing a resistance layer 6 having a plurality of apertures arranged in a lattice pattern and having light emitting members each arranged in each of the apertures, on a substrate 2 having an image display region 10 and a peripheral region 11 at an outer periphery of the image display region, such that the resistance layer extends from the image display region to the peripheral region, and such that the plurality of apertures are arranged in the image display region, providing a resistance adjusting layer having a resistance value larger than that of the resistance layer, on the resistance layer, to divide the image display region and the peripheral region into a plurality of segments, and forming a film of an electroconductive layer to cover the resistance layer and the light emitting member positioned in the segments.
