Display device and manufacturing method of display device

A display device having a plurality of pixels each including a plurality of sub-pixels, the display device comprising:

• a first substrate and a second substrate facing each other;
• a plurality of first pads disposed on the first substrate in the plurality of sub-pixels;
• a common pad disposed on the first substrate and shared by the plurality of sub-pixels;
• a plurality of first electrodes disposed on the second substrate in the plurality of sub-pixels;
• a second electrode disposed on the second substrate and shared by the plurality of sub-pixels;
• a plurality of light emitting nanorods disposed on the second substrate in the plurality of sub-pixels and in contact with the plurality of first electrodes and the second electrode;
• and
• a plurality of adhesive patterns connecting the plurality of first pads and the plurality of first electrodes and connecting the common pad and the second electrode,
• wherein the plurality of first electrodes and/or the second electrode includes a plurality of protrusions connected to the plurality of light emitting nanorods.

A method of manufacturing a display device having a plurality of pixels each including a plurality of sub-pixels, the method comprising:

• preparing a first substrate on which a plurality of first pads disposed in the plurality of sub-pixels and a common pad shared by the plurality of sub-pixels are disposed;
• forming a first electrode layer and a second electrode layer spaced apart from each other on a second substrate;
• self-aligning a plurality of light emitting nanorods by applying a direct current to the first electrode layer and the second electrode layer;
• separating the first electrode layer and the second electrode layer into a plurality of first electrodes and a second electrode, respectively, corresponding to the plurality of sub-pixels;
• and
• bonding the first substrate and the second substrate by connecting the plurality of first pads and the plurality of first electrodes and connecting the common pad and the second electrode,
• wherein the plurality of light emitting nanorods are connected to a plurality of protrusions of the first electrode layer and/or the second electrode layer and are self-aligned.
