A display device capable of early finding a sign such as misregistration or width variation of an emission layer formed by a layer transfer method, and a manufacturing method of the same are provided. In an inspection region 150 outside of an effective region 110, inspection pixels Px2 made up of organic light-emitting elements 10R, 10G and 10B are provided, and a distance W2 between the inspection pixels Px2 on both sides of a color targeted for inspection is shorter than a distance W1 between display pixels Px1 on both sides of the color targeted for inspection. Based on a change in a chromaticity or a spectrum shape of EL or PL light emission of the inspection pixel Px2, a sign such as misregistration of a red-light emission layer 15CR, a green-light emission layer 15CG, is found at an early stage.
