ABSTRACT:
In each picture element region, a first electrode provided on one side of the first substrate that is closer to the liquid crystal layer includes a plurality of sub-electrodes, whereby the liquid crystal layer forms a liquid crystal domain taking a radially-inclined orientation above each sub-electrode by an inclined electric field produced around the sub-electrode. The second substrate includes a stepped portion including an upper tier located in the reflection region, a lower tier located in the transmission region and a side surface connecting the upper tier and the lower tier to each other, the side surface of the stepped portion being located in the reflection region and covered by the second electrode. The plurality of sub-electrodes are arranged in a line in a column direction D2, and picture elements that are adjacent to each other in a row direction D1are driven with voltages of opposite polarities in each frame.
