Display device and manufacturing method therefor

A display device comprising:

• a substrate;
• a first electrode on one surface of the substrate and extending in a first direction;
• a second electrode spaced from the first electrode, on the one surface of the substrate, and extending in the first direction;
• a light emitting element on the first electrode and the second electrode, respective ends of the light emitting element being on the first electrode and the second electrode;
• a first insulating pattern on the substrate in an area between the first electrode and the second electrode and extending in the first direction;
• and
• a second insulating pattern spaced from the first insulating pattern, on the first electrode, and extending in the first direction;
• a third insulating pattern on the second electrode and spaced from the first insulating pattern and the second insulating pattern;
• a first contact electrode on the first electrode and in contact with one end of the light emitting element and the first electrode;
• and
• a second contact electrode on the second electrode and in contact with the other end of the light emitting element and the second electrode,
• wherein the first contact electrode covers the first insulating pattern,
• wherein the second contact electrode covers the third insulating pattern,
• wherein at least a portion of the first insulating pattern is on the light emitting element, and does not overlap the ends of the light emitting element in a thickness direction of the substrate,
• wherein the second insulating pattern does not overlap both ends of the first electrode in the thickness direction of the substrate, and
• wherein a thickness of the first insulating pattern is greater than a diameter of the light emitting elements.

A manufacturing method for a display device, the method comprising:

• preparing a substrate comprising a first electrode and a second electrode that are spaced from and opposing each other, and a plurality of light emitting elements on the first electrode or the second electrode;
• and
• disposing a shadow mask on the substrate and forming an insulating pattern material layer on the first electrode and the second electrode as well as on an area between the first electrode and the second electrode using the shadow mask,
• wherein the insulating pattern material layer:
• overlaps one end of the first electrode opposing the second electrode and one end of the second electrode opposing the first electrode, in a thickness direction of the substrate, and
• does not overlap an other end of the first electrode and an other end of the second electrode in the thickness direction of the substrate.
