Display apparatus and multi-screen display apparatus including the same

A display apparatus, comprising:

• a display area including a plurality of pixels arranged on a first substrate, the plurality of pixels extending in a first direction and in a second direction that is different from the first direction, wherein a width and length of the display area is the same as a width and length of the first substrate;
• a plurality of pixel driving lines disposed in the display area and coupled respectively to the plurality of pixels;
• an insulation layer covering the plurality of pixel driving lines;
• and
• a first pad part disposed over the insulation layer and electrically coupled to the plurality of pixel driving lines, respectively, wherein the first pad part comprises:
• a plurality of first pads electrically coupled to each respective pixel driving line of the plurality of pixel driving lines through respective contact holes formed in the insulation layer;
• and
• a plurality of secondary pads respectively covering the plurality of first pads.

A display apparatus comprising:

• a first display device and a second display device positioned adjacent to each other along a first direction,
• wherein each of the first and second display devices includes:
• a display area including a plurality of pixels positioned on a first substrate, the plurality of pixels arraigned having pixels extending in the first direction and pixels extending in a second direction that is different from the first direction;
• a pixel driving line disposed in the display area and coupled at least some of the plurality of pixels;
• an insulation layer covering the pixel driving line;
• a contact hole formed in the insulation layer;
• and
• a first pad assembly disposed over the insulation layer and positioned over the contact hole to be electrically coupled to the pixel driving line,
• wherein the first pad assembly includes:
• a first pad directly coupled to the pixel driving line through contact hole formed in the insulation layer;
• and
• a second pad directly coupled to and overlying the first pad.
