Abstract
A display device may include: a display area; a peripheral area which is located outside the display area and in which a black matrix is disposed; and a plurality of pixel columns including: a first pixel column including a first pixel configured to display a first color; and a second pixel column including a second pixel configured to display a second color different from the first color, wherein an absolute value of a first boundary slope of a boundary line between the first pixel column and the black matrix may be greater than an absolute value of a second boundary slope of a boundary line between the second pixel column and the black matrix, and wherein the first color may be one of white and green.
Claims15
A display device comprising:
- a display area;
- a peripheral area which is located outside the display area and in which a black matrix is disposed;
- and
- a plurality of pixel columns comprising:
- a first pixel column comprising a first pixel configured to display a first color;
- and
- a second pixel column comprising a second pixel configured to display a second color different from the first color,
- wherein an absolute value of a first boundary slope of a boundary line between the first pixel column and the black matrix is greater than an absolute value of a second boundary slope of a boundary line between the second pixel column and the black matrix,
- wherein the first color is one of white and green,
- wherein a part of the first pixel column disposed in the peripheral area overlaps the black matrix and is not completely covered by the black matrix, and
- wherein a part of the second pixel column disposed in the peripheral area completely overlaps the black matrix.
A display device comprising:
- a display area;
- a peripheral area disposed outside the display area and separated from the display area by an imaginary boundary line;
- a black matrix disposed in the peripheral area;
- and
- a plurality of pixel columns comprising:
- a first pixel column comprising a first pixel configured to display a first color;
- and
- a second pixel column comprising a second pixel configured to display a second color different from the first color,
- wherein an absolute value of a first boundary slope of a boundary line between the first pixel column and the black matrix is greater than an absolute value of a second boundary slope of a boundary line between the second pixel column and the black matrix,
- wherein an absolute value of a slope of a tangent line at which the first pixel column and the imaginary boundary line meet is smaller than the first boundary slope,
- wherein a part of the first pixel column disposed in the peripheral area overlaps the black matrix and is not completely covered by the black matrix, and
- wherein a part of the second pixel column disposed in the peripheral area completely overlaps the black matrix.
A display device comprising:
- a display area;
- a peripheral area disposed outside the display area and separated from the display area by an imaginary boundary line;
- a black matrix disposed in the peripheral area;
- and
- a plurality of pixel columns comprising:
- a first pixel column comprising a first pixel configured to display a first color;
- and
- a second pixel column comprising a second pixel configured to display a second color different from the first color,
- wherein the first pixel of the first pixel column disposed in the peripheral area does not overlap the black matrix,
- wherein the first color is one of white and green,
- wherein a part of the first pixel column disposed in the peripheral area overlaps the black matrix and is not completely covered by the black matrix, and
- wherein a part of the second pixel column disposed in the peripheral area completely overlaps the black matrix.
