[0001]

[Industrial applications]

 The present invention relates to the structure of a liquid crystal display device used for a liquid crystal display device.

[0002]

[Prior Art]

 The structure of a conventional liquid crystal display device of this type is as shown in FIGS. 3 and 4, 1A and 1B are transparent substrates, 2A and 2B are alignment films, 3 is a color filter, 4 is a black mask, 5 is a lead wiring, and 6A. , 6B is a first spacer material, 7 is a second spacer material, and 8 is a main seal.

The transparent substrates 1A and 1B are provided with a second spacer material 7 and an effective spacer disposed on the routing wiring 5 and on the main seal 8 disposed in a sparse or nonexistent location of the routing wiring 5. It is held at a predetermined interval by the first spacer material 6 within the display range.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, the main seal 8 is arranged in the same cell on the leading wiring (FIG. 3) and in a place where the leading wiring is sparse or nonexistent (see FIG. 4), and the main seal 8 Since the spacer material has the same diameter regardless of the location, there is a problem in that the thickness of the transparent substrate varies depending on whether the routing wiring is sparse or nonexistent or dense.

In addition, a load is applied to the first spacer material 6A in the vicinity of the edge in the display in a sparse or nonexistent place, and deformation is caused, resulting in a deviation in the cell thickness in the effective display, which eventually causes color unevenness. There is a problem that occurs.

The present invention has been devised in view of the problems of the above-mentioned conventional techniques, and an object thereof is to provide a structure of a liquid crystal display device capable of eliminating color unevenness near the end of the effective display range.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the structure of the liquid crystal display device according to the present invention, a color filter and a black mask are laminated on the inner surface of one side substrate, and the main seal is attached around the two opposite substrates. In a liquid crystal display element formed by enclosing a liquid crystal material between them, a part or all of the main seal is arranged so as to overlap the color filter and the black mask.

Further, a dummy seal is arranged inside the main seal so as to partially or completely overlap the color filter and the black mask.

Further, the size of the spacer of the main seal and the size of the spacer of the dummy seal inside the main seal are such that spacers having different diameters are mixed.

[0010]

[Action]

 At the locations where the black masks and color filters are placed, the routing wiring is arranged uniformly without any density. Therefore, a uniform cell thickness can be maintained by placing a main seal or a dummy seal on the black mask and the color filter laminated area.

In addition, a spacer smaller by 2 μm in thickness between the black mask and the color filter is set in the dummy seal, and in the main seal, it is set larger by the thickness of the black mask, the color filter, the alignment film and the electrode. By using the above spacer, the cell thickness inside and outside the effective display range can be controlled to ± 0.1 μm, and color unevenness near the end of the effective display range can be eliminated.
