摘要： A light-emitting element producing method includes: a step of forming a first-charge transport layer on a first electrode; a step of applying a first photosensitive resin composition, containing first quantum dots, to the first-charge transport layer, and forming a first-quantum-dot containing layer; a step of applying a second photosensitive resin composition, containing second quantum dots, to the first-quantum-dot containing layer, and forming a second-quantum-dot containing layer; a step of forming a second-charge transport layer on the second-quantum-dot containing layer; and a step of forming a second electrode on the second-charge transport layer.

摘要： Common electrodes are provided in a manner in which the common electrodes are divided into a common electrode for an odd column corresponding to a pixel electrode to which a positive video signal is applied in a certain frame period, and a common electrode for an even column corresponding to a pixel electrode to which a negative video signal is applied in the certain frame period. A common electrode driver is configured to be capable of separately applying a voltage to the common electrode for the odd column and the common electrode for the even column.

摘要： A display device includes a thin film transistor layer, a light-emitting element layer including a plurality of light-emitting elements, each including a first electrode, a function layer, and a second electrode, and each having a different luminescent color. The function layer includes a light-emitting layer and a pair of holding layers sandwiching the light-emitting layer and each including a photosensitive material. One of the first electrode and the second electrode is an anode electrode and the other is a cathode electrode. The function layer includes a hole transport layer provided between the anode electrode and one holding layer of the pair of holding layers, and an electron transport layer provided between the cathode electrode and the other holding layer of the pair of holding layers.
