Abstract
A liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer, and a plurality of columnar spacers. The pixel arrangement is a stripe arrangement including red, green and blue pixel columns. The first substrate includes TFTs, one for each pixel, wherein each TFT includes an oxide semiconductor layer. The second substrate includes a color filter layer and a light-blocking layer. The light-blocking layer includes a plurality of first shading portions extending along the column direction, and a plurality of second shading portions extending along the row direction. Each of the columnar spacers is aligned with one of the second shading portions. At least one of the red, green and blue pixel columns has first pixel boundaries, where one of the second shading portions is present, and second pixel boundaries, where none of the second shading portions present, alternating with each other in the column direction, and the second shading portions are arranged in a staggered arrangement.
