  • Publication number: 20240138176
    Abstract: A display device includes first and second light emitting regions; first and second pixel electrodes in the first and second light emitting regions, respectively; a first organic layer in the first light emitting region, including first and second light emitting layers; a second organic layer in the second light emitting region, including a third light emitting layer; a common electrode on the first and second organic layers; a wavelength conversion pattern on the common electrode, overlapping the first organic layer, and wavelength-converting light of a first color into light of a second color, different from the first color; and a light transmitting pattern on the common electrode, overlapping the second organic layer. The third light emitting layer and one of the first and second light emitting layers emit light of the first color, and another one of the first and second light emitting layers emits light of the second color.

  • Patent number: 8186297
    Abstract: A substrate processing apparatus is provided. The substrate processing apparatus includes a substrate supporting member including a spin head on which a substrate is placed, a nozzle discharging processing liquid to the substrate placed on the spin head, and a processing liquid supplying source supplying the processing liquid to the nozzle. The nozzle includes a nozzle main body that has a plurality of discrete discharging openings and an integration discharging opening. The discrete discharging openings have a slit-shaped cross section having a first length and are arrayed in series in a predetermined direction. The integration discharging opening is formed by connecting the discrete discharging openings to each other in a single slot shape having a length greater than the first length, and finally discharges the processing liquid.
