    • An exposure method for color filter substrate is provided. As shown in FIG. 7(a), exposure is performed while a substrate 20 to which a photoresist has been applied is being transported in the Y direction, to simultaneously form first layers 81 and layers 91 in first non-display regions 51 (regions indicated by hatching sloping upward to the right) and the display region, respectively, on the substrate 20. Next, as shown in (b), the substrate 20 is rotated by 90 degrees, and exposure is performed while the substrate 20 is being transported in the X direction, to form second layers 82 in second non-display regions 52 (regions indicated by hatching sloping upward to the right). Thus, dummy PSs 71 and dummy PSs 72 arranged with desired pitches and having desired shapes can be formed in the first non-display regions 51 and the second non-display regions 52, respectively.
    • 提供了一种滤色器基板的曝光方法。 如图所示。 如图7(a)所示,在施加了光致抗蚀剂的基板20在Y方向上传送的同时进行曝光,同时在第一非显示区域51(由阴影向上倾斜所示的区域)同时形成第一层81和层91 向右)和显示区域。接下来,如(b)所示,将基板20旋转90度,并且在沿X方向输送基板20的同时进行曝光, 以在第二非显示区域52(由向右倾斜的阴影指示的区域)上形成第二层82。 因此,可以分别在第一非显示区域51和第二非显示区域52中形成设置有期望的间距并具有期望形状的虚拟PS 71和虚拟PS 72。

    • A color filter which is able to form a liquid crystal display device that has few variation in display caused due to difference in exposure illuminance among exposure heads and/or misalignment in pattern position, and that is excellent in display quality, and an exposure mask used for producing the color filter are provided. A color filter 1 includes: a substrate 2; black matrixes 3 provided on the substrate 2; and a plurality of colored layers 4 which partially overlap the black matrixes 3 in at least a first direction. The widths of overlap portions 5 in which the black matrixes 3 and the colored layers 4 overlap each other in the first direction are varied over the entirety of a display area, and the degree of the variation is uniformly distributed over the entirety of the display area. As a result, even if the sizes of the overlap portions 5 are partially varied due to misalignment in position of the exposure heads and/or change of exposure condition, the partial variation is blended into the variation of the widths distributed over the entirety of the display area, so that a varied state can be prevented from becoming conspicuous as a whole.
    • 一种能够形成由于曝光头之间的曝光照度的差异和/或图案位置的不对准而导致的显示变化很小并且显示质量优异的显示品质的显示装置,以及使用的曝光掩模的滤色器 用于制造滤色片。 滤色器1包括:基板2; 设置在基板2上的黑色矩阵3; 以及在至少第一方向上与黑矩阵3部分地重叠的多个着色层4。 黑矩阵3和着色层4在第一方向上彼此重叠的重叠部分5的宽度在整个显示区域上变化,并且变化程度均匀地分布在整个显示区域上 。 结果,即使重叠部分5的尺寸由于曝光头的位置不对准和/或曝光条件的改变而部分变化,部分变化也被混合到整个宽度分布的宽度变化中 显示区域,从而可以防止变化状态整体变得显眼。

    • A liquid crystal display device is provided which prevents variation in display from being caused due to misalignment of positions of exposure heads and/or error in assembly, and which is excellent in display quality. A liquid crystal display device 1 includes: a color filter 2 and a TFT substrate 3 which are bonded so as to oppose each other; and liquid crystal (not shown) sealed in a space formed therebetween. The color filter 2 includes: a substrate 4; black matrixes 5 provided on the substrate 4; and a plurality of colored layers 6 and 7 which partially overlap the black matrixes 5 at each pixel position. Vertices of ridges 18a and 28a formed by the colored layers 6 and 7 overlapping the black matrix 5 are positioned in an area where upper edges 19a and 29a, respectively, which continue in the Y-axis direction, are shielded from light by a light shielding section 10a of the TFT substrate 3.
