The invention provides a reflection type liquid crystal device, and a projection type display and electronic equipment in which display defects caused by disclination are reduced, minimized or prevented from being produced for a highly fine liquid crystal display with a space between pixels made to be narrow to make it possible to provide a high-contrast and bright display. A liquid crystal device includes a liquid crystal layer sandwiched between a first substrate and a second substrate, and a first electrode and a second electrode formed on a face of the above-described second substrate on a side of the above-described liquid crystal layer. The above-described first electrode and the above-described second electrode are formed so that an electric field substantially parallel to the surface of the substrate with respect to the above-described liquid crystal layer can be applied thereto. The above-described first electrode is formed in a linear shape having a specified line width on the above-described second electrode with a second insulation film interposed therebetween. The above-described second electrode is formed in a rectangular shape, and at least one of the above-described first electrode and the above-described second electrode is a reflecting electrode that causes incident light coming from a direction of the above-described first substrate.

When a backlightis turned on in a dark environment, white light emerging from the surface of a light guide platepasses through a polarizerand a retardation filmenters the interior of the liquid crystal cell, passes through openings of reflective electrodesand is introduced into a liquid crystal layerThe light introduced into the liquid crystal layerpasses through a color filteremerges from the liquid crystal cell, and passes through the retardation filmand the polarizertowards the exterior. In a lighted environment, the light incident on the polarizerpasses through the liquid crystal layeris reflected by the reflective electrodeand passes through the polarizeragain and is emitted towards the exterior.

Ambient light incident upon a polarizerpasses through a liquid crystal layerand is then reflected by reflective filmsvia transparent electrodesThe reflected light passes again through the liquid crystal layerand the polarizerand is output to the outside thereby displaying an image in a reflective displaying mode. The reflective filmsare disposed at locations corresponding to the respective transparent electrodessuch that they are spaced from each other. In this structure, some ambient light passes through the spaces between adjacent transparent electrodes, however, such light is not reflected by the reflective filmstoward the outside and thus a reduction in contrast due to such reflection is prevented.

To simplify a manufacturing process of a transverse electric field mode liquid crystal display device by using a non-linear resistance element such as a TFD (Thin Film Diode) as a switching element. In a liquid crystal display device having a pair of substrates with liquid crystal interposed therebetween, one of the substrates consists of an electrode substrate. On the electrode substrate, there are provided a first group of electrodes, a second group of electrodes crossing the first group of electrodes with an insulating layer interposed therebetween, non-linear resistance elements, one end of each of the non-linear resistance elements being connected to the respective one of the second group of electrodes, and pixel electrodes opposing the first group of electrodes, each pixel electrode being connected to the other end of each of the non-linear resistance elements. Since the non-linear resistance elements have a so-called TFD (MIM) structure made of metal-insulating layer-metal, the manufacturing process is simple. Therefore, it is possible to manufacture the transverse electric field mode display device at low cost.

Electro-optical device and method of manufacturing the same

In a dark environment, light emitted by a fluorescent tubeenters a liquid crystal panel by a light guide plate, is transmitted through a transflective electrodeafter passing through a polarizerand a retardation plate, and is introduced into a liquid crystal layerfollowing coloration of light by a color filter. The light introduced into the liquid crystal layeris emitted at an observation side of the liquid crystal panel through the retardation plateand the polarizersequentially. On the other hand, in a bright environment, light from the observation side passes through the polarizerand the liquid crystal layer, and is reflected at the transflective electrodefollowing coloration of light by the color filter, whereby the light is emitted at the observation side.

The present invention provides a method of manufacturing a nonlinear element capable further improving nonlinearity of a nonlinear element, an electrooptic device, and electronic apparatus. In forming an element substrate of a liquid crystal device, an underlying layer is formed on the surface of the element substrate in the underlying layer forming step (a), and then a first metal film having a metal film containing at least Ta is formed in the first metal film forming step (b). Then, in the insulating film forming step (c), the first metal film is annealed under high pressure in an atmosphere containing water vapor to form an insulating film on the first metal film. Then, in the second metal film forming step, a second metal film is formed on the surface of the insulating film to produce a nonlinear element.
