A method of manufacturing a display device includes: a) forming a first pixel electrode and a second pixel electrode; b) forming a first light-emitting layer on the first pixel electrode; c) forming a photosensitive resin layer on the second pixel electrode and on the first light-emitting layer; d) forming a photosensitive resin pattern having an opening on the second pixel electrode and including a structural member e) forming a light-emitting material layer on the photosensitive resin pattern and on an opening bottom portion that is at least a part of the second pixel electrode and that is provided below the opening; and f) forming a second light-emitting layer on the second pixel electrode by lifting off a first lift-off portion that is a part of the photosensitive resin pattern and a second lift-off portion that is a part of the light-emitting material layer, with the structural member being left intact.

Method of manufacturing display device and display device

A display device includes: a substrate; a pixel electrode disposed on the substrate, the pixel electrode including a first portion and a second portion disposed outside the first portion, the first portion protruding to a second side opposite to a first side closer to the substrate than the second portion; a light-emitting layer disposed across the second side of the first portion and the second side of the second portion; a first edge cover disposed across the second side of a side edge portion of the first portion and the second side of the second portion, the first edge cover including an opening formed on the second side of a central portion of the first portion, the first edge cover covering an edge of the first portion; and a counter electrode including a portion disposed closer to the second side than the first edge cover.

Display device and method for manufacturing display device

A method of treating an aqueous solution containing quantum dots, the method includes: a dissolution liquid preparation step of dissolving a quaternary ammonium salt and a potassium salt in an aqueous solution containing quantum dots to prepare a dissolution liquid; a phase separation step of heating the dissolution liquid to separate the dissolution liquid into two phases, which are a quaternary ammonium salt phase containing a large amount of the quaternary ammonium salt and a potassium salt phase containing a large amount of the potassium salt, and also to cause the quantum dots to be included in either one of the quaternary ammonium salt phase and the potassium salt phase; and a fractionation step of separating the quaternary ammonium salt phase and the potassium salt phase by fractionation.
