Abstract:
1. A liquid crystal display (LCD) device comprising a TFT (thin-film-transistor) substrate mounting thereon a plurality of TFTs each having a channel in an ohmic contact layer and a semiconductor layer; a counter substrate mounting thereon a black matrix; a liquid crystal layer sandwiched between said TFT substrate and said counter substrate; a backlight unit disposed at a rear side of said TFT substrate for irradiating said TFT substrate with backlight, said counter substrate mounting thereon a light shield overlapping said channel of said TFTs as view normal to said counter substrate; and a rear shield film interposed between said channel of said TFTs and said backlight unit to overlap said channel of said TFTs s viewed normal to said TFT substrate, said channel having a channel length larger at an edge portion of said channel adjacent to one of said pixels than at a central portion thereof, whereupon leakage current of said TFT at said edge portion is suppressed.
