  • Publication number: 20160274402
    Abstract: Exemplary embodiments relate to a display device, an optical mask, and a method for manufacturing a display device using the same. The display device including: a first substrate and a second substrate facing the first substrate; a thin film transistor disposed on the first substrate; a first insulating layer disposed on the thin film transistor; and a light blocking member disposed on the first insulating layer. The light blocking member includes a spacer for maintaining a cell gap between the first substrate and the second substrate and a main light blocking portion having an upper surface that is lower than an upper surface of the spacer, and the light blocking member further includes a furrow at a border between the spacer and the main light blocking portion, the furrow having a surface lower than the upper surface of the main light blocking portion.

  • Publication number: 20160216555
    Abstract: A liquid crystal display includes a first substrate and a second substrate. A plurality of thin film transistors and a plurality of pixel electrodes connected thereto are formed on the first substrate. The second substrate faces the first substrate and includes a color filter. The color filter includes a blue color filter, a green color filter, and a red color filter corresponding to each pixel electrode. A yellow color filter is formed on at least one of the green color filter and the red color filter.
