| 1. A liquid crystal display device comprising:
a first substrate;
a second substrate opposite to the first substrate;
a liquid crystal material interposed between the first substrate and the second substrate;
a plurality of pixels including a first pixel and a second pixel that are adjacent to each other, the first pixel including
a first pixel electrode and the second pixel including a second pixel electrode, an edge of the first pixel electrode and
an adjacent edge of the second pixel electrode being separated by a gap;
a reflecting region and a transmission region at each of the plurality of pixels, the reflecting region and the transmission
region being successively formed adjacent to each other; and
a layer that sets a thickness of the liquid crystal layer in the reflecting region to be thinner than a thickness of the liquid
crystal layer in the transmission region that results in a step between the reflecting region of the first pixel and the transmission
region of the second pixel, the step including an upper flat portion, a slope portion, and a lower flat portion, the edge
of the first pixel electrode being substantially arranged on an upper portion of the slope portion of the step and the adjacent
edge of the second pixel electrode being arranged at the lower flat portion of the step.
