A manufacturing method of a display panel including a light emitting element including a first electrode, a carrier transporting layer constituted of at least one layer and a second electrode so as to layer the first electrode, the carrier transporting layer and the second electrode, and the manufacturing method includes forming the first electrode in a predetermined region on a substrate, forming an opening from which only a predetermined region of the first electrode is exposed by patterning an insulation film by carrying out an etching after forming the insulation film on the substrate including the first electrode and forming the carrier transporting layer at least on the first electrode which is exposed from the opening.

Display panel and manufacturing method of display panel

A display device comprising: a light-emitting element formed on a substrate; a driver element formed on the substrate, that controls a current flowing in the light-emitting element; a switching element that switches the driver element; and a light-blocking film formed so as to correspond to only the switching element.

Display device

A display panel includes a plurality of sets of transistors which are formed on an upper side of a substrate. An insulating film is formed to cover upper surfaces of the transistors and has a plurality of trenches formed in an upper surface thereof. A plurality of first interconnections are buried in the trenches. An interconnection insulating film covers upper surfaces of the first interconnections. A plurality of second interconnections are provided on an upper side of the interconnection insulating film. Each of a plurality of pixel electrodes is provided between two adjacent interconnections of the second interconnections. Each of a plurality of light-emitting layers is provided on one of the pixel electrodes. A counter electrode is provided on the light-emitting layers.
