  • Patent number: 8456595
    Abstract: 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.
