LCD with diffuser having diffusing particles therein located between polarizers |
摘要 |
A liquid crystal display includes a patternable diffusing layer therein positioned between the display's substrates. The diffusing (or diffuser) layer includes a host material having a plurality of particles (e.g. substantially transparent spherical balls or spacers) provided therein in order to perform a diffusion function. The refractive index np of the particles is different (i.e. DELTA n) from the refractive index nh of the host material by at least about 0.05, and DELTA n is preferably from about 0.05-0.15. In certain embodiments, photoimageable color filters, with diffusing particles embedded therein, function as discrete diffusing members across the passive substrate. In other embodiments, a substantially continuous diffusing layer with a transparent host, including spherical balls embedded therein, may be provided across the passive substrate between the substrate and the color filters. Still further, the diffusing layer with transparent host material may be provided between the common electrode and black matrix members on the passive substrate.
