    Abstract: An EL element includes a light-emitting layer (1), a color filter layer (4a-4c, 5a-5c), and a surface substrate (9). The color filter layer (4a-4c, 5a-5c) and the surface substrate (9) are located on the light extraction side. The color filter layer (4a-4c, 5a-5c) is present between transparent electrodes (3) formed on the the light-emitting layer and the surface substrate (9), and includes light-emitting portions of three primary colors and light shielding layers (6) formed between each of the light-emitting portions. The sides of the light shielding layers (6) or the light-emitting portions are covered with a metal reflective layer (7). This allows diffused light to be reflected back to each of the light-emitting portions, so that light can be extracted efficiently on the screen side. The metal reflective layer is connected electrically to the transparent electrodes and can reduce the electrical resistance value of the transparent electrodes.
