摘要： A display apparatus includes: a first substrate and a display unit. The display unit includes a display region and a transmissive region. The display unit further includes: an auxiliary layer disposed in correspondence with the transmissive region; and a second electrode disposed in correspondence with the display region and at least a portion of the transmissive region. The auxiliary layer includes a first material, the second electrode includes a second material, and the first material and the second material each satisfy Equation 1 below: ST2−ST1>0 mJ/m2, wherein, in Equation 1, ST1 is a surface energy of the first material at 25° C., and ST2 is a surface energy of the second material at 25° C.

摘要： A material-removing heater device including: a first terminal portion defining a first electrode; a second terminal portion defining a second electrode; and a heating portion which connects the first terminal portion to the second terminal portion, the heating portion heatable by a flow of electrical current from the first terminal portion to the second terminal portion to remove a portion of material of a display device. The heating portion defines a lower end surface of the material-removing heater device at which the material-removing heater device contacts the material of the display device, the heating portion disposes the lower end surface to have a concave shape, and the heating portion which is heated deforms the lower end surface from the concave shape to have a planar shape.
