Claim:
1. A liquid crystal display device, comprising: a second substrate having scan signal lines which run in an X direction and are aligned in a Y direction and video signal lines which run in the Y direction and are aligned in the X direction; and a first substrate that is provided so as to face said second substrate with a liquid crystal layer in between, with pixel regions between said scan signal lines and between said video signal lines being arranged in a matrix, characterized in that the liquid crystal display device comprises: protrusions formed in borders between adjacent pixels and protruding from said second substrate on the liquid crystal side; first electrodes made of sidewall electrodes formed on sidewalls of protrusions, and lower end side electrodes which extend from said sidewall electrodes on bottoms of the protrusions and run along said second substrate on the liquid crystal side, each of said first electrodes being made of at least a pair of sidewall electrodes formed along sides that face each other with a pixel region in between and a lower end side electrode located between the sidewall electrodes; and second electrodes made of first linear electrodes which are formed within said pixel regions on said first substrate side and run in the direction in which said first electrodes run, and second linear electrodes which are formed within said pixel regions on said second substrate side and run so as to face said first linear electrodes with said liquid crystal layer in between, wherein said first electrodes that reach from a lower side portion on said second substrate side on which said sidewall electrodes are formed to an upper side portion on said first substrate side have a height that is greater than a thickness of said liquid crystal layer in the pixel region sandwiched by said first electrodes, the liquid crystal display device has a first insulating thick film formed on said second substrate on the liquid crystal side and a first trench created in said first insulating thick film so as to run along a side of a pixel region, and a side portion of a sidewall electrode on the bottom side is integrally connected to a lower end side electrode at the bottom of said first trench.
