发明名称 Liquid crystal display device having a spacer
摘要 To provide a transverse electric field liquid crystal display device which eliminates the leakage of light and suppresses the disturbance of the electric field between the electrodes, thus enabling an image display of high quality, a liquid crystal display device has a liquid crystal panel which provides at least two kinds of color filters FIL(R), FIL(G) . . . of different colors and a black matrix BM interposed between said respective color filters on one substrate SUB2, a group of electrodes PX, CT, CT1, CT2, SD2 . . . for selecting pixels formed on the other substrate SUB1, a liquid crystal layer LC made of a liquid crystal composition sandwiched between the substrates and having a dielectric anisotropy, a polarizing plate POL1, POL2 laminated on an outer surface of at least one of the substrates, and drive means which applies drive voltages for display to a group of the electrodes. The liquid crystal display device further includes spacers SP which bridge a gap defined between opposing inner surfaces of the pair of substrates. The spacers SP are formed by bringing top portions of a protrusion SP1 having a specific resistance of less than 108 OMEGA.cm which is formed on one substrate SUB2 side and a protrusion SP2 having a specific resistance of not less than 108 OMEGA.cm which is formed on the other substrate SUB1 side into contact with each other.
