Patent ID: 6954243

Claim:
A liquid crystal display device comprising: a liquid crystal display panel including a first substrate, a second substrate, and a sealing material provided between the first and second substrates on peripheral portions of respective main surfaces thereof for sealing liquid crystal in a space therebetween, a front surface of the second substrate constituting a display surface of the panel; a backlight unit irradiating a back surface of the first substrate with light, the back surface being opposite form the display surface across the panel, the backlight unit including a light guide body which has a main surface being opposite to the back surface of the first substrate and a cold cathode fluorescent lamp disposed opposite to a side surface of the light guide body; a rectangular frame formed of a material obstructing light, having a display window exposing the display surface of the liquid crystal display panel, and covering a peripheral portion of the liquid crystal display panel around the display surface; and a molded frame having side walls in which the light guide body is inserted and holding the liquid crystal display panel in conjunction with the rectangular frame, wherein both of the first substrate and the second substrate are formed of an insulating material having sufficient optical transmissivity to make the substrates transparent, the peripheral portion of the main surface of the first substrate extends outwards from that of the second substrate at a first side and a second side transverse to the first side thereof and overlaps that of the second substrate at a third side opposite to the first side and a fourth side transverse to the third side and opposite to the second side, each said side of the first substrate and the second substrate has a side surface transverse to the back surface of the first substrate or the front surface of the second substrate respectively, the sealing material has an injection port for injecting the liquid crystal between the first and second substrates, the injection port is formed at a third side of the liquid crystal display panel, the injection port is plugged by a closing material, the third and fourth side surfaces of the first and second substrates are covered with a light shielding film and disposed above the side wall of the molded frame to be enclosed by the rectangular frame, and the light shielding film extends from the third and fourth side surfaces of the first substrate to the third and fourth side surfaces of the second substrate and covers the closing material at the third side thereof.
