PURPOSE: A liquid crystal display module is provided to prevent an optical beam from reflecting toward a liquid crystal panel due to gap between a light guide plate and optical sheets, thereby removing the bright line on the liquid crystal panel. CONSTITUTION: A support main(32) has an inner side surface formed in step surfaces. A back light unit includes a reflector(34), a light guide plate(36), first to third optical sheets(38,40,42) different in sizes, and a lamp housing. The back light unit is mounted on an inner bottom layer. A liquid crystal panel(52) is formed of upper and lower substrates(46,48) attached with upper and lower polarizing plates(44,50) respectively, and liquid crystal interposed between the upper and lower substrates. The liquid crystal panel is accumulated on the back light unit. The support main has first step parts(54) for securing the first to third optical sheets, and second step parts(56) for securing the lower substrate. The first step parts have first to third securing parts forming step heights to be correspondent to the heights of the first to third optical sheets.
