Abstract: The object of the present invention is to provide a novel liquid crystal display material having an excellent contrast ratio, a display method and a display device using the material. The present invention uses a liquid crystal display material comprising a polymer in which a liquid crystal is dispersed in a dissolvable state or a phase separable state, wherein the liquid crystal dissolves in the polymer at high temperatures and separates from the polymer at low temperatures, and a contrast ratio (B/A) of a reflectance (A) of the display material cooled from the dissolution state at a rate of 10° C./sec and a reflectance (B) of the display material cooled from the dissolution state at a rate of 4° C./sec is not less than 2. The image forming state can be maintained by controlling the cooling rate from the dissolution state to maintain the liquid crystal in translucent state.

Abstract: An electrode width of intermediate connection wiring which connects terminal electrode and common electrode is made narrower than an electrode width of terminal electrode at forming an electrode pattern on one of substrates configuring a liquid crystal display device. This enables the prevention of detrimental effect of cutting and polishing the periphery of a liquid crystal cell onto the terminal electrode. A laser irradiation process required for removing the common electrode is eliminated, and thus manufacturing cost may be reduced.

Abstract: The invention provides an array substrate for a transflective liquid crystal display device, including: a thin film transistor having gate, data and drain electrodes on a transparent substrate; an insulation layer over the substrate while covering the thin film transistor, the insulating layer having a drain contact hole exposing the drain electrode of the thin film transistor; a reflective electrode having a transmitting hole on the insulation layer; and a transparent electrode covering the reflective electrode entirely, wherein either the reflective electrode or the transparent electrode contacts the drain electrode via the drain contact hole of the insulation layer. The fabrication method is also disclosed. The resistance between the reflective electrode and the transparent electrode can be reduced, and the fabrication method can be simplified.

Abstract: A liquid crystal display has s a liquid crystal cell having a front surface serving as a viewing-side surface and a back surface, a reflecting film is attached to the back surface of the liquid crystal cell, and a light guide panel having a first major surface provided with minute irregularities and a second major surface finished in a smooth flat plane is disposed on the front surface of the liquid crystal cell with the second major surface thereof finished in a smooth flat plane in contact with the front surface of the liquid crystal cell. A light source is disposed beside aside surface of the light guide panel. When the liquid crystal display is used in a dim environment, the light source is turned on. Light emitted by the light source is guided and scattered toward the reflecting film by the light guide panel, so that the light can be transmitted efficiently by the light guide panel and the liquid crystal cell to the reflecting film.

Abstract: The invention concerns an LCD connection for a communication unit to connect an LCD to PCB. The connection includes several parts to make the connection between the LCD and the PCB reliable, but still easy and cheap to assembly. It is also easy to dismantle since the connector is neither fixed mounted to the LCD nor to the PCB. The connector includes an LCD covered with an Indium Tin Oxide (ITO) pad, an Anisotropic Conductive Foil (ACF) layer on top of the ITO pad, at least one Double Flexible Printed Circuit (DFPC) located on the ACF layer, a spring connector and a PCB. The invention also includes a method for connecting an LCD to a PCB.

Abstract: A liquid crystal display device (1) comprises a liquid crystal display panel (3) and a reflector (5) disposed on the side of the liquid crystal display panel, opposite from the visible side thereof. The liquid crystal display panel (3) comprises liquid crystal (3f) sandwiched between two transparent substrates (3a, 3b), and display electrodes (3c, 3d) made up of a transparent and electrically conductive film provided on the inner faces of the respective substrates (3a 3b). The reflector (5) is provided with protrusions (5a) formed at positions corresponding to the display electrodes (3c, 3d) on a face thereof opposite to the liquid crystal display panel (3).

Abstract: An inventive array substrate for the transflective liquid crystal display device includes a pixel electrode, a reflective electrode, and an interposed insulation layer. When the pixel electrode is under the reflective electrode, the sum of the thickness of the insulation layer and the reflective electrode is less than 0.5 micrometers. In other embodiments, upper surfaces of the reflective and pixel electrodes are on the same plane. This results from adjusting the thickness and changing the structure such as adopting a drain supplementary electrode extended from the drain electrode of the thin film transistor or positioning the pixel electrode within the transmitting hole of the reflective electrode.
