Abstract: Connection wires connecting signal wires and element-side terminals on a substrate are formed with a plurality of first parts and second parts as connection parts having predetermined widths. Further, by adjusting thicknesses of the plurality of connection parts of the connection wires, or by forming lamination wires on the first parts as the connection parts so as to attain multi-layer structures, the connection wires are arranged so as to have substantially uniform resistances. This allows a difference between a width of the broadest connection wire and a width of the narrowest connection wire to be suppressed so that the former is approximately twice the latter. Consequently, short-circuiting of a broad connection wire and wire-breaking of a narrow wire can be avoided, while the resistances of the connection wires can be made uniform.

Abstract: The present invention features designs of pixels and designs of control features for seals on AMLCD tiles optimized for tiling AMLCD flat panel displays (FPDs) which have visually imperceptible seams. The FPD structure has an image view plane which is continuous and remote from the pixel apertures or image source plane on the inside of the tiles. The image is formed on the view plane by a distributed ultra low magnification flies-eye optical system (a screen) that is integrated with the tiles, effectively excluding and obscuring an image of the seams. The innovations described herein minimize the defects on the perimeter pixels by effectively damming the waviness of the front of the seal near the perimeter pixels on the tiles. Dark space required for the seal between the interior tile edges and active regions of the pixels is decreased, as is the space allocated for wiring thereby increasing the feasible aperture ratios near the mosaic edges and all apertures.

The liquid crystal display device adopts a cholesteric liquid crystal color filter. Each portion of the cholesteric liquid crystal color filter is designed to have an adjusted order parameter according to a wavelength of a corresponding color ray. Therefore, with the variously adjusted order parameters of the cholesteric liquid crystal color filter, an increase of the color shift due to a longer wavelength is prevented.
