Abstract: Disclosed is a liquid crystal display device capable of improving a viewing angle thereof while reducing a gray scale inversion. The liquid crystal display device has a porous film aligned on a liquid crystal display panel and having a plurality of pores. The porous film has sidewalls defined by the pores and reflecting a part of light exited from the liquid crystal display panel. That is, the sidewalls reflect a first group of light, which has relatively higher luminance by passing through a short axis of liquid crystal, towards a second group of light having a relatively lower luminance by passing through a long axis of liquid crystal. Accordingly, the viewing angle of the liquid crystal display device is expanded and the gray scale inversion is reduced.

Abstract: In an array substrate, a gate line is arranged on a base substrate and extends in a first direction, and a data line is insulated from and crossing the gate line and extends in a second direction. A switching part is connected between the gate line and the data line. A pixel electrode is connected to the switching part and partially overlaps the data line. The pixel electrode has an opening, and the opening is spaced apart from the data line in a plan view.

Abstract: In a display panel, gate lines, data lines, pixel electrodes and a trap electrode are formed on a second display substrate. The gate lines are extended in a first direction, and the data lines are extended in a second direction while insulating from and intersecting with the gate lines. The pixel electrodes may have a W shape rotated in a counter-clockwise direction. The trap electrode is formed in a black matrix area among the pixel electrodes and a different voltage (e.g. a gate-off voltage) from the pixel voltage applied to the pixel electrodes is applied to the trap electrode. Thus, ion impurities in the display panel are trapped into the black matrix area, thereby removing an image sticking caused by the ion impurities.

Abstract: A light polarizer for use in an LCD includes a polarizing film, a retardation film, and an auxiliary film. The auxiliary film increases the total thickness of the polarizer such that the polarizer can be easily detached from the LCD for rework without damaging the LCD.

Abstract: A method and apparatus for manufacturing a polarizer for use in a large-sized liquid crystal display (LCD) with a size of 60 inches or more includes controlling the degree of stretching of a PVA film to have a width corresponding to a length of a long side of an LCD panel, cutting the stretched PVA film to fabricate PVA sheets, and attaching TAC films and protection films to each of the PVA sheets. Since the PVA film is fabricated into the PVA sheets, it is possible to fabricate a polarizer without changing the widths of the TAC films and protection films. Therefore, costs can be reduced that are associated with facility investment for manufacturing polarizers for LCDs having a size of 60 inches or more.

Abstract: A multiple height mounting assembly is provided for installation of a drinking fountain at a selected one of multiple different mounting positions spaced vertically above a floor or ground surface associated therewith. The mounting assembly includes a mounting plate adapted for secure affixation to a wall structure at a selected vertical elevation position thereon. The mounting plate defines a central aperture for passage of plumbing lines. A set of bolt-receiving mounting holes is formed in the mounting plate in surrounding relation to the central aperture for accommodating subsequent drinking fountain installation onto the mounting plate at a selected one of multiple different vertical elevation positions. In one preferred form, the mounting plate includes multiple apertures each with associated bolt-receiving mounting holes to accommodate installation of multiple drinking fountains thereon.

A display device according to the present invention comprises: a light source; an image forming means for forming an image using a light emitted from the light source and an input image signal; a projection means for projecting an image formed in the image forming means on a screen; a displacement means for displacing an image displayed on the screen to be displaced; a driving means for driving the displacement to be moved; and an input signal applying means for applying an input signal to the driving means for the displacement means to be rotated in a predetermined direction. According to the present invention, different images are displayed on a screen periodically. It seems that the greater number of pixels is used than the real number in a sense of sight.
