Claim 19:
20. The display panel of claim 19, wherein the reference light is light incident from the area of the emission layer toward a boundary between a first side surface of the partition configured to define the first opening and a bottom surface of the partition connected to the first side surface, and
the reference incident angle is given by the following equation:, tan

where the DT1 is a distance between the emission layer and the functional layer, and
the DT2 is a distance between a first point, at which the reference light is emitted, inside the first emission area and a second point of the functional layer to which the reference light is incident, when viewed in a thickness direction of the display panel,
wherein the first refractive index (n1) and the second refractive index (n2) satisfy the following equation:, sin
