Abstract
Provided are a display apparatus and a method of manufacturing the display apparatus. A color filter layer including at least a red color filter, a green color filter, and a blue color filter is disposed on a first substrate. A black matrix is disposed on the color filter layer. A color filter overlapped unit where the red, green and blue color filters are overlapped is disposed in a black matrix area corresponding to the black matrix. The color filter overlapped unit has a lower reflectivity with respect to an external light than the other color filters. The color filter overlapped unit is formed in the black matrix area, and the color filter overlapped unit is formed by overlapping the blue, red and green color filters in order, and, thus, can prevent mixing of colors and reduce reflection with respect to an external light.
Claims18
A display apparatus comprising:
- a color filter layer which is disposed on a first substrate and includes at least a red color filter, a green color filter, and a blue color filter;
- a black matrix disposed on the color filter layer;
- a color filter overlapped unit where the red, green and blue color filters are overlapped in a black matrix area corresponding to the black matrix;
- and
- a plurality of sub-pixels defined by the black matrix and including a white sub-pixel,
- wherein the color filter layer further includes a color filter segment unit disposed on the white sub-pixel.
A display apparatus comprising:
- a white sub-pixel;
- a colored sub-pixel part including a red sub-pixel, a green sub-pixel and a blue sub-pixel;
- a black matrix area between the white sub-pixel and the colored sub-pixel part;
- a color filter layer disposed in the colored sub-pixel part and the black matrix area;
- and
- a color filter segment unit disposed on the white sub-pixel, wherein the color filter layer includes a color filter overlapped unit disposed in the black matrix area and having a structure in which color filters of the color filter layer are stacked.
A display apparatus comprising;
- a color filter structure on a first substrate;
- an overcoat layer covering the color filter structure;
- and
- a black matrix, on the overcoat layer, having black matrix segments that provide boundaries to separate and define at least four sub-pixel regions,
- wherein the color filter structure is configured to have different color layers, with a first color layer at a first sub-pixel region, a second color layer at a second sub-pixel region, a third color layer at a third sub-pixel region, and a stack of the first through third color layers at the boundaries between adjacent sub-pixel regions, and
- the stack of first through third color layers is configured by overlapping of adjacent color layers with a particular stacked order that effectively minimizes reflectivity of external light without using a polarization plate.
