Abstract: Electroluminescence elements mounted on a substrate of an OLED display device are sealed by a protective film made of synthetic resin with chemical reaction curing in place of a sealing can. The protective film is formed such that a thickness thereof is equal to or larger than a thickness of the substrate. Alternatively, the protective film is formed by laminating a plurality of resin films which differ in one of the water absorption ratio, the elastic modulus and the hardness. With respect to the protective film which is formed of a plurality of laminated films, compared to the protective film at the electroluminescence element side, the protective film which covers the former protective film has the water absorption ratio, the elastic modulus or the hardness larger than the water absorption ratio, the elastic modulus or the hardness of the former protective film. Due to such a constitution, it is possible to reduce the thickness of the OLED display device without damaging the moisture-proof property of the electroluminescence elements.

Abstract: Light emitted by a backlight can be prevented from leaking through a chamfered portion of a front window of a liquid crystal display device.An upper polarizing plate is bonded over the counter substrate, and a front window is bonded over the upper polarizing plate with a UV-curable resin adhesive. The front window is chamfered and a light shielding member is formed on the chamfered portion. The UV adhesive exists between the chamfered portion and the surface of the upper polarizing plate or the counter substrate, and an outer end of the polarizing plate exists at a point outer than an outer end of the front window. Since the light shielding member for the chamfered portion is formed, light from the backlight does not penetrate from the chamfered portion. Thus, light leakage at a periphery of a screen can be prevented even when the view angle is large.

Abstract: A liquid crystal display device can suppress the local temperature elevation of a liquid crystal in the vicinity of drivers. On a liquid-crystal-side surface of one substrate out of substrates which are arranged to face each other in an opposed manner while sandwiching a liquid crystal therebetween, a switching element which is operated in response to scanning signals from a gate signal line, a pixel electrode to which video signals from a drain signal line are supplied via the switching element, and a reference electrode which generates an electric field between the reference electrode and the pixel electrode are mounted on each pixel region of the liquid-crystal-side surface. The video signals from the drain signal line are generated by a driver chip mounted on one substrate. A light transmittivity of the liquid crystal layer is set to take a minimum value when a voltage is not applied between the pixel electrode and the reference electrode. A maximum amplitude of voltage of the video signals is set to a value not more than a voltage necessary for setting a relative transmittivity of the liquid crystal layer to 90%.
