Patent ID: 7688410

Claim:
A display panel comprising: a lower substrate comprising: a plate comprising a transmission region through which a light may pass and a reflection region from which a light may be reflected; a switching element formed on the plate; an insulating layer formed on the plate to cover the switching element and the insulating layer formed in the reflection region; a transmission electrode electrically connected to the switching element, the transmission electrode being formed in the transmission region; and a protrusion formed on the transmission electrode, the protrusion divides the transmission electrode of the transmission region into a plurality of transmission portions; an upper substrate facing the lower substrate; and a liquid crystal layer disposed between the lower substrate and the upper substrate, wherein the protrusion is extended to reach a boundary of the transmission region so that the transmission portions are completely isolated from each other, and the protrusion is formed from the same layer as the insulation layer, and a height of the protrusion is no more than a thickness of the insulating layer of the reflection region.
