A liquid crystal display device, that is, an LCD device, comprising: a first substrate and a second substrate; gate and data lines (200, 300) provided on the first substrate and arranged to cross each other to define a plurality of pixels, wherein the gate lines extend in a first direction and the data lines extend in a second direction different from the first direction; a gate electrode provided in each of the plurality of pixels which protrudes from the gate line 200 in the respective pixel; a pixel electrode provided in each of the plurality of pixels on the first substrate; a common electrode provided on the first substrate and adapted to produce an electric field between itself and each of the pixel electrodes; an auxiliary line extending in the second direction on the first substrate 100 which is connected to the common electrode and adapted to reduce the resistance of the common electrode, wherein the auxiliary line is arranged to cross over each of the gate lines and to extend over one of the data lines; a column spacer provided between the first substrate and the second substrate to maintain a cell gap, wherein the column spacer overlaps one of the data lines and is fixed to the second substrate but can move freely on the first substrate; and two movement-stopping walls (550a, 550b) provided on the first substrate and extending parallel to each other in the first direction and which are adapted to restrict the range of movement of the column spacer which is arranged in between the two movement-stopping walls (550a, 550b), wherein the first of the two movement-stopping walls is spaced apart from the gate line while overlapping the gate electrode 210, whereas the second of the two movement-stopping walls overlaps the gate line; wherein the two movement-stopping walls (550a, 550b) are spaced apart from the auxiliary line; and further wherein the two movement-stopping walls (550a, 550b) are arranged to form island structures by crossing over from one to three data lines without being in contact with the auxiliary line. a first substrate and a second substrate; gate and data lines (200, 300) provided on the first substrate and arranged to cross each other to define a plurality of pixels, wherein the gate lines extend in a first direction and the data lines extend in a second direction different from the first direction; a gate electrode provided in each of the plurality of pixels which protrudes from the gate line 200 in the respective pixel; a pixel electrode provided in each of the plurality of pixels on the first substrate; a common electrode provided on the first substrate and adapted to produce an electric field between itself and each of the pixel electrodes; an auxiliary line extending in the second direction on the first substrate 100 which is connected to the common electrode and adapted to reduce the resistance of the common electrode, wherein the auxiliary line is arranged to cross over each of the gate lines and to extend over one of the data lines; a column spacer provided between the first substrate and the second substrate to maintain a cell gap, wherein the column spacer overlaps one of the data lines and is fixed to the second substrate but can move freely on the first substrate; and two movement-stopping walls (550a, 550b) provided on the first substrate and extending parallel to each other in the first direction and which are adapted to restrict the range of movement of the column spacer which is arranged in between the two movement-stopping walls (550a, 550b), wherein the first of the two movement-stopping walls is spaced apart from the gate line while overlapping the gate electrode 210, whereas the second of the two movement-stopping walls overlaps the gate line; wherein the two movement-stopping walls (550a, 550b) are spaced apart from the auxiliary line; and further wherein the two movement-stopping walls (550a, 550b) are arranged to form island structures by crossing over from one to three data lines without being in contact with the auxiliary line.
