    Abstract: An organic EL display panel includes pixels and an interlayer insulation film on a thin film transistor layer. The interlayer insulation film includes contact holes which each correspond to one of the pixels. A bank is a grid that defines apertures. One of the contact holes is beneath each of the apertures. A first organic light-emitting layer is disposed in each of the apertures that corresponds to one of the pixels of a first color. A second organic light-emitting layer is disposed in each of the apertures that corresponds to one of the pixels of a second color. In each of the apertures in which one of the first and second organic light-emitting layers is disposed, a contact hole region is above the contact hole. A first-material layer comprising a same material as the first organic light-emitting layer and a second-material layer comprising a same material as the second organic light-emitting layer are superimposed in each contact hole region.

  • Patent number: 7714328
    Abstract: The present invention provides an electro-optical device capable of achieving an increased light emission efficiency and an enhanced visibility. An organic electroluminescents (EL) display device has a plurality of material layers including a luminescent layer. In a plurality of material layers layered in the direction of light emission from the luminescent layer, first and second insulating interlayers are disposed between a substrate, which is positioned at the outermost surface, and the luminescent layer. The first and second insulating interlayers have a refractive index lower than that of the substrate. Accordingly, by forming predetermined materials having a low refractive index, the resulting low refractive index layers have a low dielectric constant, and consequently, the capacity between wires can be reduced.
