To make it difficult to view streak unevenness in alignment generated at the boundary of alignment layers even when an alignment-layer material is applied onto a color-filter substrate several times to form an alignment layer. When an alignment-layer material is applied onto a color-filter substrate 1 having color filters (R, G, and B) on the surface with a droplet discharge head 3 to form an alignment-layer train 4a, the lateral front end L1 of the train 4a is formed on the color filter (B) displaying blue. When the alignment-layer material is then applied to the following alignment-layer application train to form an alignment-layer train 4b, the lateral rear end L2 of the train 4b is overlapped with the lateral front end L1 of the preceding alignment-layer train 4a to form an overlapped portion 4c. Since the overlapped portion 4c is formed on the color filter (B) displaying blue which has the lowest visibility of the three primary colors of light, streak unevenness in alignment generated at the boundary is difficult to view from the exterior.
