  • Patent number: 9201264
    Abstract: A display panel includes a substrate, a partition formed on the substrate and defining a plurality of openings, a plurality of color filters formed in the openings and having a substantially uniform thickness within each respective opening, and a spacer formed on the partition. The color filters and the spacer are formed through inkjet printing. The color filters have the substantially uniform thickness by the partition having a height which is greater than the thickness of the color filters during the inkjet printing. The height of the partition may be in a range of about 1.5 to about 2 times the thickness of the color filter.

  • Publication number: 20080212220
    Abstract: In a color filter substrate and a method for manufacturing the color filter substrate, the color filter substrate includes a base substrate, a first blocking pattern, a second blocking pattern and color filters. The base substrate includes a plurality of pixel areas. The first blocking pattern extends along a direction of the base substrate. The second blocking pattern crosses the first blocking pattern and includes a passage portion through which the base substrate is exposed to connect the pixel areas adjacent to each other along the direction. Color filters are formed in the pixel areas. Accordingly, the uniformity of the color filters and the reliability of the color filter's quality and manufacturing process may be enhanced so that display quality may be enhanced.
