PROBLEM TO BE SOLVED: To provide a display device wherein the separation of a portion formed on the surface of a stepped part of an insulation film of a reflection layer from the insulation film is suppressed. SOLUTION: An EL device (display device) 101 includes: a plurality of pixels 2; a common feeder 11 supplying a signal or power to each of the plurality of pixels 2; an organic planarizing film 22 covering the common feeder 11; and a reflection layer 23 covering the organic planarizing film 22 and having a side face section 23a one-dimensionally crossing the common feeder 11. The cross-sectional shape of the feeder 11 is a trapezoidal shape having a base 11b and side face parts 11a, which is inclined inside toward the upper part. The angle A1, formed by the side face part 11a of the cross-sectional shape along the side face part 23a of the reflecting layer 23 of the common feeder 11 and the base 11b, is smaller than the angle A2 formed by the side-face part 211a of a cross-sectional shape, in the width direction of a common feeder 211 and the base 211b.
