<p>There is provided a liquid crystal display apparatus having a color-filter on array (COA) structure capable of increasing aperture ratio and reducing contact failure. The liquid crystal display apparatus comprises an active matrix substrate (10) having a structure in which a lower layer conductive portion (TFT) (20), a color filter layer (30), and an upper layer conductive portion (pixel electrode) (15) are stacked in this order on an insulating substrate (11); an opposing substrate (40); and a liquid crystal layer (50) sandwiched between the substrates. The color filter layer (30) includes coloring sections (32a, 32b) and a barrier membrane(BM) (31) for partitioning the coloring sections. The barrier membrane (BM) (31) has a shape in which a plurality of aperture sections (33a, 33b) where the coloring sections are disposed and a link aperture section (34) for linearly linking the plurality of aperture sections are formed. The upper layer conductive portion (pixel electrode) (15) is connected, through a contact hole (17) formed in a region overlapping the link aperture section (34), to the lower layer conductive portion (TFT) (20). The link aperture section (34) makes the surface tension of ink, i.e., coloring material work, so that it is possible to effectively prevent the ink from penetrating up to the contact hole (17).</p> |
