Claim Text:
1. A display substrate comprising: a base substrate; a switching element on the base substrate and including a gate electrode, a source electrode and a drain electrode; a protecting layer on the switching element, in which is defined a first hole which exposes the drain electrode; an organic layer on the protecting layer, in which is defined a second hole which exposes a side surface of the protecting layer which defines the first hole, and exposes a top surface of the protecting layer which is adjacent to the side surface of the protecting layer which defines the first hole; a second pixel electrode which is electrically connected to the drain electrode via the first and second holes; and a first pixel electrode between the organic layer and second pixel electrode which is electrically connected to the drain electrode via the first and second holes, the first pixel electrode overlapped by the second pixel electrode, wherein the entire top surface of the protecting layer exposed by the second hole of the organic layer makes contact with the second pixel electrode.
