A reflection type display according to the present invention, which has a first substrate, a second substrate and a display medium interposed therebetween, includes: pixel electrodes arranged in rows and columns on the first substrate; canning lines each disposed adjacent to a respective one column of the pixel electrodes on the first substrate; a plurality of nonlinear resistance two terminal devices for electrically connecting each scanning line to the pixel electrodes of the respective one column; and signal lines disposed on the second substrate to cross the scanning lines. Each pixel electrode includes first and second metal layers and is insulated from the respective one of the scanning lines by an insulating layer. The materials of the first and second metal layers are different, and the material for the first metal layer has the reflectance higher than that of the material of the second metal layer. Each nonlinear resistance two terminal device includes a pair of electrodes and a nonlinear resistance layer provided between each pixel electrode and the insulating layer, one of the electrodes being a portion of the respective one of the scanning lines while the other is the second metal layer, the nonlinear resistance layer being in contact with the electrodes through a through hole provided in the insulating layer.

Reflection type display

A two-terminal non-linear resistive device including a first electrode, a second electrode, and a zinc sulfide layer interposed therebetween. The zinc sulfide layer contains at least one transition metal element as an impurity. The zinc sulfide layer is formed by sputtering using a sintered ZnS target including the transition metal element or a sintered ZnS target including the transition metal sulfide.

Two-terminal non-linear resistive device and a method for producing the

A liquid crystal display apparatus of the invention includes: a pair of substrates and a liquid crystal layer sandwiched therebetween; a plurality of scanning signal formed on one substrate; a plurality of data signal lines arranged perpendicular to the scanning signal lines and formed on the other substrate; pixel electrodes respectively at crossing portions in which the scanning signal lines cross the data signal lines; and nonlinear resistive two-terminal devices respectively provided between the pixel electrodes and the scanning signal lines. Scanning signals each including a selection period and a non-selection period are applied to the scanning signal lines, and data signals are applied to the data signal lines. While these signals are applied to the scanning signal lines and the data signal lines, liquid crystal application signals are applied to the liquid crystal layer via the two-terminal devices. Each liquid crystal application signal has a first voltage in a writing period as a first half of the selection period and a second voltage in a regulating period as a latter half of the selection period. The first voltage is determined in accordance with video data. The second voltage is a voltage at which part of the electric charge, which is charged into the liquid crystal layer in the writing period, is released.

Liquid crystal display apparatus

A transmission type or projection type liquid crystal display device includes a light source and an active matrix type liquid crystal display panel provided with a thin film transistor arrangement. A shielding film is included for cutting off light incident upon the thin film transistor arrangement from the light source. Electrode terminals of the liquid crystal display panel and outputs of driving LSI circuits are connected to each other by flexible substrates with the connected portions between the electrode terminals of the liquid crystal display panel and the flexible substrates protected by a connected portion protecting resin. The liquid crystal display device is further provided with a light shielding device for covering at least the protecting resin portion of the liquid crystal display panel, so as to prevent light of the light source from entering the region of the connecting portion protecting resin.
