A method of manufacturing a display apparatus includes discharging liquid droplets in a first area of a substrate, moving a discharge part by a first distance along a side of the substrate and discharging the liquid droplets in a second area of the substrate, and moving the discharge part by a second distance along the side of the substrate and discharging the liquid droplets in a third area of the substrate. The first distance is different from the second distance.

Method of manufacturing display apparatus

A display device includes a display panel and a first quantum dot layer disposed on the display panel, wherein the first quantum dot layer includes a first portion and a second portion extending from a side of the first portion in a first direction. The second portion has a width less than a width of the first portion in a second direction intersecting the first direction.

Display device including quantum dot layer

An inkjet printing method includes moving an inkjet head to discharge ink to a substrate including printing row areas, discharging ink to a first printing row area and a second printing row area among the printing row areas, discharging ink to a third printing row area among the printing row areas and the second printing row area, and discharging ink only to the first printing row area.

Printing method

An inkjet circulation apparatus may include at least one inkjet printer including a supplier into which an ink is injected, a discharger connected to the supplier, and discharging the ink injected from the supplier, and a drain connected to the discharger and the supplier, and injecting the ink in the discharger into the supplier, at least one collector capable of containing an inert gas and the ink discharged from the discharger, and a contact member sealing between the discharger and the collector.

Inkjet circulation apparatus

Disclosed are display panels and methods of manufacturing substrates. The display panel comprises a lower display substrate that includes a plurality of light emitting elements, and an upper display substrate that includes a color control layer and is on the lower display substrate. The color control layer includes a plurality of walls each of which includes a wall base including an organic material and a reflective layer including a metallic material, and the color control layer also includes a plurality of color control parts which are disposed between the plurality of walls and at least one of which includes a quantum dot. The reflective layer surrounds at least a portion of a sidewall of the wall base, which results in an increase in luminous efficiency and an improvement in brightness.

A display device may include a first substrate, a first color conversion unit, a second color conversion unit, a light diffusion unit, and a first wall. The first color conversion unit is located on the first substrate. The second color conversion unit is disposed on the first substrate and is spaced from the first color conversion unit. The light diffusion unit is disposed between the first color conversion unit and the second color conversion unit. The first wall is disposed between the first color conversion unit and the light diffusion unit. The first color conversion unit includes a first-color conversion layer. The first-color conversion layer overlaps two pixel regions.

Display device

A photo-luminescent display device includes: a backlight to output a backlight; a first substrate and a second substrate facing each other; a pixel electrode disposed on the first substrate; a light amount control layer disposed in a space between the first substrate and the second substrate to control a transmittance of the backlight; a first light conversion portion disposed on the second substrate to convert a wavelength of the backlight; a light diffusion portion disposed adjacent to the first light conversion portion to diffuse the backlight; and a barrier surrounding the first light conversion portion. The light diffusion portion and the barrier include a unitary structure.
