Abstract: A display panel includes: first and second substrates, each including a display area and a peripheral area in a plan view; and a sealing portion disposed between the first and second substrates. An edge of the display panel includes straight-lined and shaped edges, and the shaped edge includes a curved portion. An edge surface of the first substrate at the straight-lined edge, an edge surface of the second substrate at the straight-lined edge and an edge surface of the sealing portion at the straight-lined edge collectively define a first convex surface, an edge surface of the first substrate at the shaped edge, an edge surface of the second substrate at the shaped edge and an edge surface of the sealing portion at the shaped edge collectively define a second convex surface, and shapes of the first and second convex surfaces are different from each other.

Abstract: An exposure mask includes a first transmission portion, a second transmission portion, and a blocking portion. The first transmission portion is configured to, when illuminated with light, transmit the light at a first energy level. The first transmission portion is disposed in association with formation of a first contact hole in an underlying layer. The second transmission portion is configured to, when illuminated with the light, transmit the light at a second energy level. The second transmission portion is disposed in association with formation of a second contact hole in the underlying layer. The blocking portion is configured to block the light, and is disposed in association with a boundary region between a first region and a second region of the underlying layer. The second transmission portion is further configured to enable the second contact hole to be formed deeper into the underlying layer than the first contact hole.

Abstract: A display device includes a pixel including a first electrode and a second electrode and having first capacitance formed between the first electrode and the second electrode; a power supply to provide the first electrode with a third power voltage including an alternating wave form and to provide the second electrode with a second power voltage; and a sensor to sense a touch current flowing between the first electrode and the second electrode in response to the touch driving signal.
