ABSTRACT:
The present invention provides a liquid crystal display device having a color-filter on array structure, which can improve an aperture ratio and reduce connection defects. The present invention is a liquid crystal display device including the first substrate, the second substrate, and a liquid crystal layer interposed between the first and second substrates, the first substrate having a structure in which a lower conductive part, a color filter layer, an upper conductive part are stacked in this order on an insulating substrate, wherein the color filter layer includes a colored part and a partition for partitioning the colored part, the partition is formed in such a way that a plurality of openings and a coupling opening are formed, the colored part being arranged in the plurality of openings, the coupling opening linearly coupling the plurality of openings with each other, and the upper conductive part is connected to the lower conductive part through a contact hole, the contact hole being formed in a region overlapping with the coupling opening.
