Abstract: A backlight unit prevents the display quality degradation of a LCD device and improves the long-term reliability thereof. The unit comprises at least one fluorescent lamp having a first end and a second end; a first cable or wire connected to the first end of the lamp; and a second cable or wire connected to the second end of the lamp.

Abstract: An LCD device suppresses the display quality degradation due to the mechanical strain of an LCD panel, the optical leakage through the gap between the frame-like portion of the casing (the shield front) and the panel, and the dust penetrated through the gap. The window of the casing or shield front is formed to be larger than an outer dimension of the second substrate. A sheet having electrical conductivity and a light-blocking property is placed in an approximately entire region sandwiched by an outer portion of the second substrate and a frame-like portion of the casing that surrounds the window. An electrically conductive layer is formed directly on or indirectly by way of an optical member on a surface of the second substrate, the surface being located on a side of the window. The sheet is connected to an inner surface of the frame-like portion of the casing and to the layer at the outer portion of the second substrate or on the member.

Abstract: A method of forming a semiconductor thin-film constitutes an alignment mark in a laser annealing process. A first laser beam is irradiated to a semiconductor thin-film to form a first irradiated region. A second laser beam, which is coaxial with the first laser beam, is irradiated to the thin-film in such a way as not to overlap with the first irradiated region, thereby forming a second irradiated region and a non-irradiated region. An alignment mark is formed by using an optical constant difference between the second irradiated region and the non-irradiated region. The second laser beam may be irradiated to the thin-film in such a way as to overlap with the first irradiated region, where an alignment mark is formed by using an optical constant difference between the first and second irradiated regions or between the second irradiated region and the non-irradiated region. Preferably, the thin-film is made of a-Si or poly-Si.

In order to effectively restrict the battery effect between a reflective electrode and a transparent electrode, a surface of the organic film is put in a plasma-processing and then is washed by a washing liquid. Thereafter, the transparent electrode is formed and then the reflective electrode such as a double layer electrode of the aluminum layer and the molybdenum layer are formed.

Abstract: Active matrix display device includes connection wirings passing through a sealing material. The connection wirings are sandwiched between inorganic interlayer insulation film and an organic planarizing film. The organic film is selectively removed at a seal region to form opening portions to expose the inorganic film and to be filled with a sealing material. The sealing material contacts the lower layer inorganic interlayer insulation film in the bottom of an opening portion to increase the adhesive strength.

Abstract: Light exposure areas 103 and light masking areas 104 in a sole reticle are arrayed in alternation to one another in both the longitudinal and transverse directions. Substrate is exposed to light by multi-domain light exposure using this reticle so that the respective areas of the reticle exposed to light with respective shots A to B, B to C . . . , N to M are not adjacent to one another in the boundary portions of the reticle shifted for executing the respective shots, thus relaxing the difference in illuminance between the respective shots and the difference in finish of the boundary portions of the shots, such differences becoming imperceptible to human eyes upon displaying liquid crystal display apparatus.

Abstract: Light is input into an incident surface portion from a fluorescent lamp, and most of the light propagates in repetition directions. Since a length of an emission portion of the fluorescent lamp is shorter than that of the incident surface portion, there are areas to which no light propagates and dark portions generate in the repetition directions of a string of prisms. Since these dark portion generate out of the display area, a display quality is improved.
