Display device, mask assembly, and apparatus for manufacturing display device

A display device comprising:

• a plurality of first intermediate layers having quadrangular shapes and spaced apart from each other;
• a plurality of second intermediate layers having quadrangular shapes and spaced apart from each other, the plurality of second intermediate layers facing the plurality of first intermediate layers, respectively;
• and
• a plurality of third intermediate layers having quadrangular shapes and spaced apart from each other, the plurality of third intermediate layers facing the plurality of first intermediate layers, respectively, and being spaced apart from the plurality of second intermediate layers,
• wherein a distance from a side of each of the first intermediate layers to a respective one of the second intermediate layers and a distance from a side of each of the first intermediate layers to a respective one of the third intermediate layers are different from each other.

A mask assembly comprising:

• a mask frame;
• and
• a plurality of mask sheets arranged on the mask frame under tension and sequentially arranged with each other along a side of the mask frame,
• wherein each of the plurality of mask sheets has a plurality of openings,
• wherein some of the plurality of openings are tilted in one direction with respect to a tensile direction of the mask sheet, the other ones of the plurality of openings are tilted in a different direction from the some of the plurality of openings, and centers of at least three of the plurality of openings are arranged in a serpentine shape in one direction.

An apparatus for manufacturing a display device, the apparatus comprising:

• a chamber in which a display substrate is arranged;
• a deposition source arranged in the chamber to supply a deposition material into the chamber;
• and
• a mask assembly arranged to face the deposition source and via which the deposition material is to pass to the display substrate in a pattern form,
• wherein the mask assembly comprises:
• a mask frame;
• and
• a plurality of mask sheets arranged on the mask frame under tension and sequentially arranged with each other along a side of the mask frame,
• wherein each of the plurality of mask sheets has a plurality of openings,
• wherein some of the plurality of openings are tilted in one direction with respect to a tensile direction of the mask sheet, the other ones of the plurality of openings are tilted in a different direction from the some of the plurality of openings, and centers of at least three of the plurality of openings are arranged in a serpentine shape along one direction.

A display device comprising:

• a first sub-pixel;
• a second sub-pixel arranged to face the first sub-pixel;
• a third sub-pixel arranged to face the first sub-pixel and spaced apart from the second sub-pixel;
• and
• a spacer arranged between the first sub-pixel and the second sub-pixel and/or between the first sub-pixel and the third sub-pixel,
• wherein a distance from a side of the first sub-pixel facing the second sub-pixel and the third sub-pixel to the second sub-pixel is different from a distance from the side of the first sub-pixel to the third sub-pixel.

A display device comprising:

• a first sub-pixel;
• a second sub-pixel arranged to face a side of the first sub-pixel;
• and
• a third sub-pixel arranged to face the side of the first sub-pixel and spaced apart from the second sub-pixel,
• wherein a side of at least one selected from the first sub-pixel, the second sub-pixel, and the third sub-pixel is convex or concave, and
• the second sub-pixel and the third sub-pixel are adjacent to each other and are arranged to face the same side of the first sub-pixel.
