Abstract
An organic light-emitting display having an anti-reflective and inert cathode is provided. The cathode is made of a diamond-like carbon material to reduce ambient light reflection and increase contrast. The diamond-like carbon material is an opaque and inert material, so the cathode is anti-reflective and inert.
