Abstract: PURPOSE: A panel structure of an organic electroluminescent display element is provided to improve display quality of a luminous element by conducting a surface treatment to an external light reflected by a metal electrode which is used as a cathode electrode material. CONSTITUTION: An unevenness formed part(12) resides on a surface of a substrate(10) in an observed direction. If light is incident, an irregular reflection is caused. By way of example, sunlight or an external light source is emitted on the unevenness formed part(12) of the substrate, the incident light causes the irregular reflection, such that the incident light does not reach a cathode electrode. Therefore, reflection by the cathode electrode disappears. The light reflected on the substrate is not a reflection in a uniform direction but the irregular reflection. As a result, an amount of light reflected on a point on which an actual observation is carried out is drastically reduced. Only light emitted on an organic electroluminescent display element can be observed on the observed point. Accordingly, color and contrast of the display are improved. At this time, it should be considered that loss of the light emitted on the organic electroluminescent display element should be minimized.
