Abstract
A display panel including a plurality of pixels. Each pixel includes: a light emitting element; a pixel circuit having a driving transistor connected to the light emitting element in series; a data line to which a data current is supplied through the pixel circuit; a scanning line for selecting the pixel circuit; a first insulation film to cover the data line; and a second insulation film made of a material different from the first insulation film, to cover the data line and the first insulation film, wherein the following expression is satisfied. C: parasitic capacitance of whole path to data line through pixel circuit; ∈: vacuum dielectric constant; ∈: relative dielectric constant of first insulation film; D: first insulation film thickness; ∈: relative dielectric constant of second insulation film; D: second insulation film thickness.
