  • Publication number: 20080174725
    Abstract: A liquid crystal display has spacers for maintaining a liquid crystal layer and a cell gap between a substrate and an opposite substrate and also has regions either within a single pixel or over two or more pixels. The spacers are of columnar shape elongated from the substrate to the opposite substrate or the other way round, and the columnar spacers are provided in regions in which the liquid crystal layer is thinnest among those regions in which the liquid crystal layer varies in thickness. The structure makes the liquid crystal display having two or more different cell gaps to stably maintain those cell gaps and produces good quality displays.

  • Publication number: 20070257871
    Abstract: The display apparatus of the present invention includes a plurality of condensing elements 54a provided between a lighting device and a display panel 100. A first substrate 10 of the display panel 100 is placed on the side of a display medium layer 23 facing the lighting device while the second substrate 11 is placed on the observer side thereof. Each pixel element Px has a transmission region Tr for display in the transmission mode using light 41 incident from the lighting device, and the first substrate 10 has a transparent electrode region defining the transmission region Tr on the side facing the display medium layer 23. Each condensing element 54a is placed to correspond to the transmission region Tr of the pixel element Px so as to form the converging point of light outputted from the lighting device at a position closer to the observer with respect to the display medium layer 23.

  • Patent number: 7248235
    Abstract: A display includes in each of display areas: a reflective area containing a non-light-emitting display element for effecting a display by means of a liquid crystal display element reflecting external light; and a light-emitting area containing a light-emitting display element for effecting a display by means of an organic EL element directly modulating external light, the reflective area and the light-emitting area being ordered in some manner. The display further includes a first substrate and a second substrate positioned opposite to each other, and the light-modulating element and the light-emitting element are both provided between the first substrate and the second substrate. Thus, a display and a method of manufacturing thereof can be offered which allows for reduction in size and cost and delivers excellent visibility from outdoors to indoors.
