Substrate for use in manufacturing display device and method for forming element on substrate
A substrate is for use in manufacturing a display device. The substrate includes a first area that corresponds to pixel positions. The substrate further includes a second area adjacent to the first area. The substrate further includes a first mark disposed in the second area, wherein a first virtual line corresponds to the first mark. The substrate further includes a second mark disposed in the second area and spaced from the first mark, wherein a second virtual line corresponds to the second mark and intersects the first virtual line at a virtual reference point. The substrate further includes an indicator disposed in the second area, spaced from the first mark and the second mark, and corresponding to an opening of a mask, wherein a positional relation between the virtual reference point and a point of the indicator represents a positional relation between the substrate and the mask.
1. A substrate for use in manufacturing a display device, the substrate comprising:
a first area corresponding to a plurality of pixel positions;
a second area adjacent to the first area;
a first mark disposed in the second area, wherein a first virtual line corresponds to the first mark;
a second mark disposed in the second area and spaced from the first mark, wherein a second virtual line corresponds to the second mark and intersects the first virtual line at a first virtual reference point; and
a first indicator disposed in the second area and spaced from each of the first mark and the second mark.
2. The substrate claim 1 , further comprising a first-colored layer having a first color, formed of an organic material, and disposed in a first pixel position of the plurality of pixel positions, wherein the first indicator is formed of the organic material.
3. The substrate of claim 1 , further comprising a first-colored layer having a first color and disposed in a first pixel position of the plurality of pixel positions, wherein the first virtual line overlaps the first-colored layer and overlaps the first indicator.
4. The substrate of claim 3 , wherein the first indicator corresponds to a first opening of a mask, and wherein a positional relation between the first virtual reference point and a point of the first indicator represents a positional relation between the substrate and the mask, the substrate further comprising:
a third mark disposed in the second area and spaced from each of the first mark, the second mark, and the first indicator, wherein a third virtual line corresponds to the third mark and intersects the second virtual line at a second virtual reference point that is spaced from the first virtual reference point;
a second indicator disposed in the second area, spaced from each of the first mark, the second mark, the third mark, and the first indicator, and corresponding to a second opening of the mask; and
a second-colored layer having a second color different from the first color and disposed in a second pixel position of the plurality of pixel positions, wherein the third virtual line overlaps the second-colored layer and overlaps the second indicator.
5. The substrate of claim 4 , wherein each of the first virtual line and the third virtual line extends in a first direction, and wherein the first mark is aligned with the third mark in a second direction that is different from the first direction.
6. The substrate of claim 5 , wherein a first side of the second mark is longer than a second side of the second mark and extends in the second direction.
7. The substrate of claim 1 , wherein a center point of the first indicator coincides with the first virtual reference point.
8. The substrate of claim 1 , further comprising:
a third mark disposed in the second area and spaced from each of the first mark, the second mark, and the first indicator; and
a fourth mark disposed in the second area and spaced from each of the first mark, the second mark, the third mark, and the first indicator,
wherein the first virtual line further corresponds to the fourth mark,
wherein the second virtual line further corresponds to the third mark,
wherein the first indicator is disposed between the first mark and the fourth mark, and
wherein the first indicator is disposed between the second mark and the third mark.
9. The substrate of claim 8 ,
wherein the first mark is aligned with the second mark in a first direction,
wherein the first mark is aligned with the third mark in a second direction different from the first direction, and
wherein the third mark is aligned with the fourth mark in the second direction.
10. The substrate of claim 8 , wherein a distance between a center the first mark and a center of the third mark is equal to a multiple of a double of a distance between a center of a first pixel position of the plurality of pixel positions and a center of a second pixel position of the plurality of pixel positions, the second pixel position immediately neighboring the first pixel position.
