Abstract:
A display panel includes an EL panel section, a CF panel section, and a sealing resin layer. In the EL panel section, the surface of a sealing layer has a projected and recessed shape in a Z-axis direction as a whole, wherein a light-emitting region corresponding to a region between banks is a recessed section, and a non-light-emitting region corresponding to a top portion of the bank is a projected section. The sealing resin layer includes a first sealing resin layer and a second sealing resin layer. Prior to performing heating or light irradiation in a step of forming the first and second sealing resin layers, the viscosity of a second non-fluid resin constituting the second sealing resin layer is lower than the viscosity of a first non-fluid resin constituting the first sealing resin layer.
