A display backplate and a manufacturing method thereof, and a display device are provided. The display backplate includes a base substrate and a pixel defining layer provided on the base substrate, the pixel defming layer defines a plurality of sub-pixel openings, an accommodation groove is provided at a surface of the pixel defining layer facing away from the base substrate, and the accommodation groove is located between two adjacent sub-pixel openings.

The present invention provides a display panel, a manufacturing method thereof and a display apparatus. The display panel includes a substrate, a light-emitting element, and a pixel defining layer. The light-emitting element includes a cathode, an anode and a light-emitting layer, the pixel defining layer defines a plurality of openings, the light-emitting layer is disposed in the openings and covers a predetermined area on a side of the pixel defining layer facing towards the openings, and hydrophilicity of the pixel defining layer at each position of the predetermined area is substantially identical.

Provided are a compound of Formula 1; an organic electric element comprising a first electrode, a second electrode, and an organic material layer formed between the first electrode and the second electrode, comprising a compound of Formula 1 in the organic material layer; and an electronic device comprising the element, which has lowered driving voltage and increased luminous efficiency and life time.

The present specification relates to an ink composition including: a compound represented by Formula 1; and a solvent represented by the Formula 2, and a method for manufacturing an organic light emitting device formed by using the ink composition.

A panel repairing method includes detecting a defective portion of a panel, providing primary ink, which is ejected from an ink ejection pin, onto a first portion of the defective portion, spreading the primary ink in a direction parallel to a plane defined on the panel, temporarily curing the primary ink, providing secondary ink, which is ejected from the ink ejection pin, onto a second portion of the defective portion disposed adjacent to the first portion, and curing the primary ink and the secondary ink.

The inventive concept provides a substrate treating control method. The substrate treating control method includes discharging a droplet to a substrate in which a relative position to the head unit changes from a nozzle of a head unit, and wherein a correction value is applied at a discharge timing of the nozzle until a preset discharge cycle among a discharge cycle of the droplet discharged by the nozzle.

An ink used in forming a functional layer of a self-luminous element by a printing method, the ink including a functional material and a mixed solvent. The mixed solvent includes solvents each having different vapor pressures. The functional material is dissolved or dispersed in the mixed solvent. A solvent that has a lowest vapor pressure among the solvents has a viscosity of at least 53 mPa.Math.s, and a viscosity of the mixed solvent is 15 mPa.Math.s or less.

A method of manufacturing a display device includes: discharging ink onto a substrate including a main partition wall for partitioning a color filter area and a dummy accommodation area adjacent to the color filter area; generating main position information by detecting a position of the first erroneous ink discharged on the main partition wall; disposing a hydrophobic plate so as to be adjacent to the first erroneous ink, based on the main position information; bringing the hydrophobic plate into contact with the main partition wall; and then moving the hydrophobic plate to the dummy accommodation area, to accommodate the first erroneous ink in the dummy accommodation area.
