Patent ID: 7956962

Claim:
A display panel, comprising: a first display substrate; a second display substrate facing the first display substrate; and a liquid crystal layer arranged between the first display substrate and the second display substrate, wherein the first display substrate comprises: a first substrate including a main pixel area having a plurality of sub pixel areas, wherein the main pixel area comprises a transmission area to transmit a first light applied thereto, and a reflection area to reflect a second light applied thereto; a first insulating layer formed on the first substrate in the sub pixel areas; a plurality of transmission electrodes arranged at the sub pixel areas of the first substrate and coupled with each other; a reflection electrode arranged in at least one of the sub pixel areas; and a second insulating layer formed on the first insulating layer under the reflection electrode and exclusively in the reflection area, wherein the stacked combination of the first and second insulating layers forms a stepped portion, wherein the transmission electrode comprises a first area on the first and second insulating layers that corresponds to the reflection area, a second area on the first substrate corresponding to the transmission area, and a third area surrounding a side surface of the second insulating layer, wherein the reflection electrode is arranged on the first area of the transmission electrode to create a step difference between the reflection area and the transmission area so that liquid crystal molecules of the liquid crystal layer are aligned at different angles from each other in relation to an interface between the reflection area and the transmission area, wherein the reflection electrode is surrounded by the sub pixel area in a plan view to be separated from an adjacent reflection electrode.
