Patent number: 9201264Abstract: 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.

Patent number: 8896790Abstract: A liquid crystal display according to an exemplary embodiment of the present invention includes: a substrate; a partition formed on the substrate and defining a pixel; a plurality of protrusion members formed with the same material as the partition on the substrate, and disposed with a linear plane shape inside the pixel defined by the partition; and a color filter filled inside the pixel defined by the partition. Accordingly, in the liquid crystal display according to an exemplary embodiment of the present invention, a plurality of transparent protrusion members are formed in the pixel defined by the partition such that movement of color filter ink dripped through an Inkjet method is controlled such that a color filter may be planarized on the whole surface of the pixel.Type: GrantFiled: June 10, 2009Date of Patent: November 25, 2014Assignee: Samsung Display Co., Ltd.Inventors: Yi-Seop Shim, Dong-Yoon Lee, Tae-Gee Min, Seong-Gyu Kwon, Jae-Hoon Kim

Patent number: 8456595Abstract: The present invention relates to a display device and a method for manufacturing the display device. The display device includes at least one partition formed on a lower display panel. A color filter may fill a region defined by the partitions. A first upper passivation layer is formed on the color filter, and a second upper passivation layer is formed on the first upper passivation layer and the partitions such that the LCD structure is planarized. In the display device, the height of the partition is sufficiently high to prevent mixing of the colors of neighboring pixel filters, and the process margin of the spacer and the light blocking member may be ensured. The partitions can be formed with multiple layers having different widths such that the mixture of colors between the neighboring pixels may be prevented, and the color reproducibility may be increased.Type: GrantFiled: June 11, 2012Date of Patent: June 4, 2013Assignee: Samsung Display Co., Ltd.Inventors: Gwan-Soo Kim, Jae-Hoon Kim, Seong-Gyu Kwon, Tae-Gee Min, Sang-Hun Lee, Yi-Seop Shim, Sun-Young Chang

Publication number: 20110019140Abstract: A display panel according to the present invention includes a first insulating substrate with a gate line and a data line formed thereon. A thin film transistor is connected to the gate line and the data line and a partition is formed according to the gate line and the data line defining a color filter filling region. Color filter is formed as a convex shape since both circumferences of upper portion and lower portion of the partition are larger than that of center portion. A color filter is formed in the filling region. A passivation layer is formed on the color filter and the partition and a pixel electrode on the passivation layer connected to the thin film transistor through a contact hole punching the passivation layer and the color filter.Type: ApplicationFiled: October 16, 2009Publication date: January 27, 2011Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jae-Hoon Kim, Seong-Gyu Kwon, Yi-Seop Shim, Tae-Gee Min
