摘要： A display apparatus includes a substrate, organic electroluminescence units, and a lens sheet. The lens sheet includes a sheet base and lenses protruding from a surface of the sheet base. A transparent substrate is above the lens sheet, and a bonding layer that includes a resin bonds the lenses to the transparent substrate. Either the substrate or the organic electroluminescence units include an alignment mark. The lens sheet includes a groove formed between the lenses in the sheet base. The groove is used for alignment with the alignment mark. The resin covers a surface of each of the lenses and is filled into the groove. A boundary area between the sheet base and each of the lenses, which is located between a surface of a lens and the groove, is covered by the resin.

摘要： A display panel apparatus includes a substrate and an organic electro-luminescence unit that includes an array. The array is above the substrate and includes a red, a green, and a blue pixel. A glass layer is above the organic electro-luminescence unit. A resin layer is between the glass layer and the organic electro-luminescence unit. A surface of the resin layer that is on a side toward the organic electro-luminescence unit includes concaves. Each of the concaves is concaved toward the glass layer and corresponds to one of the pixels. Lens resins are each in one of the concaves and include a surface that is substantially coplanar with the surface of the resin layer. A refractive index of the lens resin in the concave that corresponds to the blue pixel is greater than a refractive index of the lens resin in the concave that corresponds to the red pixel.

摘要： An organic EL element includes a substrate and a light refractive layer, a first transparent electrode layer, an insulation layer, a hole transport layer, and a photosensitive resin layer stacked above the substrate. A luminous function layer is above the hole transport layer in a recess defined by the photosensitive resin layer. A second transparent electrode layer is above the luminous function layer. The light reflective layer, the first transparent electrode layer, the insulation layer, and the hole transport layer are formed above the substrate in a region isolated by the photosensitive resin layer. The photosensitive resin layer comprises a material that absorbs incident light of a predetermined wavelength. The first transparent electrode layer, the insulation layer, the hole transport layer, and the photosensitive resin layer each have a reflectance value that is between a local minimum value and a neighborhood value of the local minimum value.

摘要： A light-emitter includes a first electrode layer, a second electrode layer, and a light-emitting layer located between the first and second electrode layers. A gradient index lens is located proximate to the second electrode layer opposite the light-emitting layer and comprises a plurality of concentric parts. The concentric parts are grouped into a central zone and annular zones. Each annular zone includes at least two of the concentric parts. One of the concentric parts included in each annular zone has a refractive index different from a refractive index of another of the concentric parts. A wavelength of light emitted from the light-emitting layer is greater than a radius of the central zone and a width of each annular zone. An effective refractive index of each annular zone decreases in an outward direction from a center of the gradient index lens.

摘要： Provided is a display panel device including a pixel unit including a luminescent layer, and a lens that covers a luminescent region of the luminescent layer placed above the pixel unit and that transmits light emitted from the luminescent layer. The height between a luminescent face of the luminescent region and an apex of the lens is uniform along the straight line in the long axis direction of the luminescent region. Furthermore, at both end parts of the lens, a cross-section of the light emitting side corresponding to the long axis direction of the luminescent region has a shape of an elliptic arc having a predetermined curvature.
