Abstract: The present invention provides an organic EL display panel manufacturing method which is capable of forming a desired organic film or the like with high accuracy without imparting damages to a substrate and an organic film and an organic EL display panel which is manufactured by the method. An opening portion which corresponds to a panel pattern region of a display panel is formed in a vapor deposition mask. The opening portion has a bottom surface in the inside of a recessed surface which is retracted from a surface on which the vapor deposition mask is brought into contact with the substrate. The opening portion of the vapor deposition mask is spaced apart from the substrate with a predetermined gap space and evaporated particles from an evaporating source are vapor-deposited to the substrate through the opening portion.

Abstract: The present invention relates to a method of manufacturing a transflective liquid crystal display device including a color filter substrate having a plurality of pixels, each including a reflective display part and a transmissive display part, and retardation plates each built in areas on a principal surface of the color filter substrate opposed to a liquid crystal layer, which correspond to the reflective display parts.

Abstract: In the present invention, to realize a liquid crystal display device of high-definition transflective IPS system comprising an inner retardation plate (retardation layer) in a reflective display unit, the retardation layer is formed of liquid crystal monomers with acrylates containing a polymerization initiator and either one or both of a triplet quencher and a radical quencher added.

Abstract: The organic electroluminescence display apparatus of the present invention comprises a first and second substrates, the former being coated with banks for separating pixels, a lower electrode, organic light-emitting layer and upper electrode of a transparent material in this order, and the latter being coated with a color filter and electroconductive shadow pattern, wherein the organic light-emitting layer surrounded by the banks for separating pixels faces the color filter, and the first and second substrates face each other in such a way that the upper electrode over the banks for separating pixels is electrically connected to the electroconductive shadow pattern. This structure connects at least one of the upper electrode and electroconductive shadow pattern to a power supply point, to control ununiform emitted light brightness which may result from voltage drop at the upper transparent electrode.

Abstract: For lasting stable vapor deposition of a material for a long term, the present invention provides the vapor deposition crucible comprising an evaporation chamber defined by a container part of the material and an orifice plate controlling vapor pressure of the material evaporated therein, and a pressure-controlling chamber defined in a space between the orifice plate and a discharge plate through which the material is discharged to the exterior of the vapor deposition crucible. A protrusion extending outwardly from the pressure-controlling chamber and having a second opening on its distal end may be provided on the upper surface of the discharge plate, and a heater may be provided on the side surface of the protrusion to oppose the side surface of the protrusion with an insulation mechanism provided at a position higher than the heater but lower than the second opening.

Abstract: At least one of an organic emitting layer, an electron injection layer and an electron transfer layer for pixels of an organic electroluminescence panel is formed from a deposition material by deposition via mask holes of a multilayer metal mask. The multilayer metal mask has a first metal layer on the side of a transparent substrate for forming the organic electroluminescence panel and a second metal layer on the side of a supply source of the deposition material, which metal layers are different in material. The second metal layer is made of a thick plate of magnetic material. The area of each first mask hole of the first metal layer is made equal to or smaller than that of each second mask hole of the second metal layer. Such a configuration can provide a metal mask forming organic electroluminescence devices with high reliability, high mechanical strength and high performance. Thus, a high-definition and high-quality organic electroluminescence display panel can be realized.
