摘要： An insulating layer is formed on a plurality of electrodes formed on a plastic film substrate, the insulating layer having a plurality of electrode connecting holes formed therein. Electrodes of the plurality of electrodes are selectively connected to an external circuit via respective ones of the plurality of connecting holes. Conductive color filter layers are formed on the thus-connected electrodes by an electrochemical method. A value obtained as a result of subtracting a width of each one of the plurality of electrode connecting holes from a width of a respective one of the plurality of electrodes is large so that a position of the electrode connecting hole is maintained to correspond to a position of the electrode even when the plastic film substrate expands or contracts maximally.

摘要： A reflection type liquid crystal display (LCD) made up of polymer dispersion type display elements each having a liquid crystal dispersion film in which liquid crystals are dispersed in a tridimensional microstructure implemented by a polymer or similar resin. Selective light reflecting or diffusing means introduces forwardly scattered light components from scattering pixels again into a liquid crystal layer without effecting non-scattering pixels. Hence, high reflection intensity and, therefore, high contrast is achieved. A light source unit is positioned such that at least a part of illumination light is reflected in the reflection angle range of the selective reflecting means. Hence, forward scattering with high scattered light intensity can be used, insuring extremely light white display.
