摘要:
A liquid crystal display panel includes a counter substrate having a counter electrode and a multi-layered dielectric film both formed thereon, and an array substrate formed with pixel electrodes and thin-film transistors serving as switching elements. A layer of polymer dispersed liquid crystal material containing a UV-curable resin component and a liquid crystal component is sealingly sandwiched between the counter and array substrates. A light shielding film is formed over each thin-film transistor. The multi-layered dielectric film is a laminated structure of alternating thin-films of SiO.sub.2 and HfO.sub.2. Since the multi-layered dielectric film is of a nature capable of transmitting UV-rays of light therethrough, the UV-curable resin component positioned underneath the multi-layered dielectric film can be cured during the manufacture. Also, since the multi-layered dielectric film is of a nature capable of reflecting light of a visible region, it serves as a black matrix, reflecting the visible light modulated by the display panel. Black beads are used to keep the film thickness of the liquid crystal layer at a predetermined value. Preferably, a dielectric thin-film having a relative dielectric constant smaller than that of the liquid crystal material is formed on signal lines for transmitting signals to the thin-film transistors, to thereby accomplish an electromagnetic shield. Where color filters are to be formed on the pixel electrodes, those color filters may be formed on the signal lines to accomplish the electromagnetic shield.
