An object of the present invention is to regulate the thickness of a liquid crystal layer between faces of substrates more uniformly and accurately than the prior arts, to eliminate an orientation disturbance caused in a rubbing treatment and to prevent a display performance from degraded, by introducing columnar spacers which have a firm adhesion force to an active matrix substrate. On an active matrix substrate which has switching elements arranged in a matrix form and pixel electrodes, columnar spacers are formed in vicinities of the switching elements on gate lines or source lines connected to the switching elements, or formed on the switching elements. Further, for giving a rubbing process to a resin film for an orientation film which is formed on the active matrix substrate, a rubbing direction is set to be a direction where an orientation-disturbed region formed in the rear of the columnar spacers does not overlap the pixel electrode substantially.

[What is claimed is:] [1.]a liquid crystal layer, and an active matrix substrate and a counter substrate for interposing the liquid crystal layer therebetween, the active matrix substrate having at least switching elements and pixel electrodes arranged in matrix form;columnar spacers for regulating a space between the substrates, which spacers are attached to respective portions of a liquid-crystal-layer-side surface of the active matrix substrate, the portions having irregularities and an at least partially tapered cross-section;wherein the columnar spacers have a taper angle in accordance with the at least partially tapered shape of the portions of the liquid-crystal-layer-side surface of the active matrix substrate; andwherein each of a plurality of said spacers is located in accordance with rubbing or orientation direction on one of said substrates, wherein respective orientation-disturbed regions adjacent to respective spacers do not substantially overlap one or more pixel electrodes.
