Abstract: An optical mask includes a light-to-heat conversion layer with an improved temperature profile. The optical masks may comprise a light-transmitting base substrate; a first reflective pattern layer which is formed on the light-transmitting base substrate comprising a first opening portion transmitting light emitted from under the light-transmitting base substrate and a first reflective portion reflecting the light; a second reflective pattern layer which is formed over the first opening portion comprising a second opening portion overlapping a first area of the first opening portion and a second reflective portion overlapping a second area of the first opening portion; and a light-to-heat conversion pattern layer which is formed on the light-transmitting base substrate, being disposed in the first area of the first opening portion, absorbing at least a part of the light, and converting the light absorbed into heat.

Abstract: In an aspect, an organic light emitting diode display including: a substrate; a first electrode and an auxiliary electrode positioned on the substrate and separated from each other; an absorption electrode positioned on the auxiliary electrode; an organic emission layer positioned on the first electrode and having a contact hole exposing the auxiliary electrode and the absorption electrode; and a second electrode positioned on the organic emission layer and connected to the auxiliary electrode and the absorption electrode through the contact hole is provided. In an aspect, the organic light emitting diode (OLED) display may minimize the voltage drop of the driving power passing through the large-sized electrode of the thin film for driving the organic emission layer, and may simplify the removal process of the organic emission layer on the auxiliary electrode by adding the absorption electrode on the auxiliary electrode.
