Display device and method of manufacturing the same

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

• exposing a first exposure region of an exposure mask;
• exposing a second exposure region of the exposure mask;
• and
• exposing a third exposure region of the exposure mask,
• wherein the exposure mask includes a first pad open region, a second pad open region, a third pad open region, and a fourth pad open region arranged along a first direction,
• wherein each of the first pad open region and the third pad open region includes a first pad slit portion,
• wherein each of the second pad open region and the fourth pad open region includes a second pad slit portion symmetrical to the first pad slit portion with respect to a line extending in a second direction, crossing the first direction, between the second pad slit portion and the first pad slit portion,
• wherein the first exposure region includes the first pad open region, the second pad open region, and the third pad open region,
• wherein the second exposure region includes the second pad open region and the third pad open region, and
• wherein the third exposure region includes the second pad open region, the third pad open region, and the fourth pad open region.

A display device comprising:

• a first substrate;
• and
• a driving pad disposed on the first substrate and including a first pad portion and a second pad portion alternately arranged along a first direction,
• wherein each of the first pad portion and the second pad portion includes a first pad region and a second pad region,
• wherein the first pad regions of the first and second pad portions include a first side and a second side opposite to the first side,
• wherein the second pad region of the first pad portion is disposed at the first side of the first pad region of the first pad portion, and the second pad region of the second pad portion is disposed at the second side of the first pad region of the second pad portion, and
• wherein each first pad region is wider than each second pad region.
