  Subsequently, for example, a photosensitive resin containing a red pigment (thickness of about 1 μm) is formed on the entire substrate on which the black matrix 15 is formed by spin coating, and then patterned by photolithography to form a red layer. 16R is formed (colored layer forming step). Further, for green (G) and blue (B), the same process as that for the red layer 16R is performed to provide the green layer 16G and the blue layer 16B, thereby forming the color filter F.

  Here, since one side (lower side in FIG. 7) of the peripheral edge of each colored layer (16R, 16G, and 16B) constituting the color filter F is formed in a step shape by each linear portion S, a plurality of those One of the linear portions S can be easily matched with each inner peripheral edge (the lower side of the opening region A) of the black matrix 15. Thereby, in the lower side of each opening region A of the black matrix 15, it is possible to reliably configure the matching portion M that coincides with the peripheral edge (lower side) of each colored layer (16R, 16G, and 16B).

  Thereafter, a part of the color filter F overlapping with the drain electrode 2b is removed by etching to form a contact hole.

  Further, a transparent conductive film (thickness of about 100 nm to 200 nm) such as an ITO film is formed on the entire substrate on the color filter F in which the contact holes are formed by sputtering, and then patterned by photolithography to obtain pixel electrodes. 4b is formed.

  Finally, a polyimide resin is applied to the entire substrate on which the pixel electrode 4b is formed by a printing method, and then a rubbing process is performed to form an alignment film (not shown).

  As described above, the active matrix substrate 20b of this embodiment can be manufactured.

<Counter substrate manufacturing process>
First, a transparent conductive film (thickness of about 100 nm) such as an ITO film is formed on a transparent substrate 10b such as a glass substrate by a sputtering method using a mask to form the common electrode 8b.

  Further, a polyimide resin is applied to the entire substrate on which the common electrode 8b is formed by a printing method, and then a rubbing process is performed to form an alignment film (not shown).

  As described above, the counter substrate 30b of this embodiment can be manufactured.

<Panel manufacturing process>

  Subsequently, after the active matrix substrate 20b and the counter substrate 30b are bonded together, an empty cell is formed by curing the sealing material.

  Finally, a liquid crystal material is injected between the active matrix substrate 20b and the counter substrate 30b constituting the empty cell by a vacuum injection method, and then the liquid crystal injection port is sealed with a UV curable resin to form the liquid crystal layer 40. To do.

  As described above, the liquid crystal display device 50b of this embodiment can be manufactured.

Since it has the overlapping part L which forms a convex part on the surface, although the alignment defect of the liquid crystal layer 40 is liable to occur due to the concave part or convex part, the liquid crystal layer 40 is caused by the concave part or convex part. The capacitor line 1b provided on the active matrix substrate 20b is superimposed on a region where alignment defects are likely to occur, and this region directly contributes to display. Since longer, it is possible to suppress a decrease in display quality.
