Abstract
A substrate (100) includes a resin material. A first stacked film (210) is configured by laminating multiple layers and is formed on a first surface (102) of the substrate (100). A light-emitting unit (140) is formed over the first stacked film (210) and includes an organic layer. A second stacked film (220) is configured by laminating multiple layers and covers the light-emitting unit (140). A third stacked film (310) is configured by laminating multiple layers and is formed on a second surface (104) of the substrate (100). The third stacked film (310) is the same stacked film as the first stacked film (210), and the fourth stacked film (320) is the same stacked film as the second stacked film (220).
