1. A display apparatus comprising: a first substrate and a display unit,
wherein the display unit comprises a display region and a transmissive region, with an insulating layer disposed on the display region and the transmissive region, a first opening in the insulating layer overlapping the display region and a second opening in the insulating layer distinct from the first opening overlapping the transmissive region,
the display unit further comprises: an auxiliary layer disposed in the second opening overlapping the transmissive region; and a second electrode disposed in the first opening overlapping the display region and above the auxiliary layer in at least a portion of the transmissive region,
the auxiliary layer comprises a first material,
the second electrode comprises a second material,
the first material comprises about 20 at % or more of fluorine, and
the first material and the second material each satisfy Equation 1 below:
ST2−ST1 >0 mJ/m2  <Equation 1>
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.
