Claim Text:
1. A liquid crystal display device comprising: a first substrate provided with a plurality of first electrodes, each including a wall-shaped electrode and a planar electrode, and the first substrate further provided with a second electrode; and a second substrate disposed so as to be opposite to the first substrate via a liquid crystal layer, wherein regions of pixels, each having the wall-shaped electrode and the planar electrode for a pixel electrode and a corresponding part of the second electrode for a common electrode, are arranged in a matrix, and the liquid crystal layer is driven by an electric field in an in-plane direction of the first substrate, applied between each of the plurality of first electrodes and the second electrode, wherein a step difference is formed on a side of the first substrate facing the liquid crystal layer for each of the pixel regions, wherein the wall-shaped electrode is formed at a side wall surface of the step difference excluding an area on a top surface of the step difference and the planar electrode extends from an edge of the wall-shaped electrode along a main surface of the first substrate, wherein the second electrode includes a linear conductive film forming a linear electrode extending along the main surface of the first substrate without connection to any electrode elevating from the linear electrode in a direction toward the liquid crystal layer, wherein the wall-shaped electrode and the planar electrode are electrically connected to each other, wherein a black matrix is provided above the top surface of the step difference, and wherein the second electrode faces the liquid crystal layer via an alignment layer.
