发明名称 Liquid crystal display device
摘要 For suppressing a brightness irregularity and contrast deterioration in a displaying screen of a liquid crystal display device which comprises a pair of substrates at least one of which is transparent, at least two kinds of color filters being formed on one of the pair of substrates, a black matrix being provided between the color filters, a group of electrodes being formed on either one of the pair of substrates, a layer of liquid crystal compounds sealed between the pair of substrates, due to noise electrical field appearing therein or unevenness of a cell gap between the pair of substrates, the present invention provides a columnar spacer having smaller resistivity than that of the liquid crystal compounds in a part of an area on the one of the pair of substrates which is hidden by the black matrix.
