In other words, the number of cell regions 262 defined by the light shielding pattern 260 matches the number of cell regions 162 defined by the light shielding pattern 160. However, the present invention is not limited to this. As described above, when the number of pixel cells in the pixel array 204 and the pixel array 104 does not match, the number of cell regions 262 defined by the light shielding pattern 260 and the number of cell regions 162 defined by the light shielding pattern 160 are reduced.

In this way, the pixel array 204, the pixel array 104, the light shielding pattern 160, and the light shielding pattern 260 can have the same periodic pattern. The material of the light shielding pattern 260 is, for example, a black resin or a light shielding metal, and is preferably composed of a low reflection material. The light shielding pattern 260 is arranged corresponding to the color filter array 250, and detailed description thereof will be described later.

  In general, the positions of the scanning line 120 and the data line 130 are in the opaque region in the pixel array 204. Therefore, the light shielding pattern 260 is generally arranged corresponding to the scanning line 120 and the data line 130 so as not to adversely affect the image display quality.

That is, each of the plurality of cell regions 262 defined by the light shielding pattern 260 corresponds to the plurality of color filter patterns of the color filter array 250. It should also be understood by those skilled in the art that the arrangement of the color filter patterns in the color filter array can be adjusted according to the actual design and usage demand. Therefore, the color filter array 250 of the present invention is not limited to that shown in FIG.

  As described above, when it is not necessary to use an additional mask, the first embodiment of the present invention uses the dummy light shielding pattern 170 arranged in the filter layer 108 to cause the light shielding pattern 160 and the filter in the filter layer 108. Since the moire phenomenon caused by the light shielding pattern 260 in the layer 208 can be reduced, higher display quality can be provided, and the user's visual discomfort can be reduced.

<Fourth embodiment>
The display device of the fourth embodiment is realized by using the display device 1000 shown in FIG. The display device of the fourth embodiment is almost the same as the display device of the first embodiment.

The description here is omitted.

  FIG. 5 is a schematic plan view of a filter layer according to an embodiment of the present invention. The filter layer of FIG. 5 includes a color filter array 350, a light shielding pattern 360, and a dummy light shielding pattern 370.

  As shown in FIGS. 1, 2, and 5, the light shielding pattern 360 defines a plurality of cell regions 362 corresponding to the pixel cells 140 on the second substrate 110. That is, in the fourth embodiment, the number of cell regions 362 defined by the light shielding pattern 360 and the number of cell regions 262 defined by the light shielding pattern 260 in FIG.

  Further, as shown in FIGS. 4 and 5, the light shielding pattern 360 includes a part of the light shielding patterns 364 arranged in the Y direction corresponding to the part of the light shielding patterns 264 and a part of the light shielding patterns. Corresponding to H.266, a part of the light shielding pattern 366 arranged along the X direction. In the space, some light shielding patterns 364 may completely or partially overlap the scanning lines 120, and some light shielding patterns 366 may completely or partially overlap the data lines 130. . In this way, the pixel array 204, the pixel array 104, the light shielding pattern 360, and the light shielding pattern 260 can have the same periodic pattern. The material of the light shielding pattern 360 is, for example, a black resin or a light shielding metal, and is preferably composed of a low reflection material. The light shielding pattern 360 is arranged corresponding to the color filter array 350, and a detailed description thereof will be described later.

  In general, the positions of the scanning line 120 and the data line 130 are in the opaque region in the pixel array 104. Therefore, the light shielding pattern 360 is generally arranged corresponding to the scanning line 120 and the data line 130 so as not to adversely affect the image display quality.

  The color filter array 350 is arranged corresponding to the pixel array 104.

Specifically, as shown in FIG. 5, in each cell region 362, the dummy light shielding pattern 370 is a stripe pattern that divides the cell region 362 into three subcell regions 372. That is, in the transmissive display panel 100 of the fourth embodiment, one pixel cell 140 in the pixel array 104 corresponds to one cell region 362 and three subcell regions 372. From another viewpoint, since the light shielding pattern 360 and the light shielding pattern 260 have the same periodic pattern, one cell region 262 in the display panel 200 corresponds to one cell region 362 in the transmissive display panel 100. In addition, it corresponds to three subcell regions 372. Although the dummy light shielding pattern 370 shown in FIG. 5 divides the cell region 362 into three subcell regions 372, the present invention is not limited to this.

In the space, some light shielding patterns 664 may completely or partially overlap the scanning lines 120, and some light shielding patterns 666 may completely or partially overlap the data lines 130. . In this way, the pixel array 204, the pixel array 104, the light shielding pattern 660, and the light shielding pattern 260 have the same periodic pattern. The material of the light shielding pattern 660 is, for example, a black resin or a light shielding metal, and is preferably composed of a low reflection material. Further, the light shielding pattern 660 is arranged corresponding to the color filter array 650, and detailed description thereof will be described later.

  In general, the positions of the scanning line 120 and the data line 130 are in the opaque region in the pixel array 104. Therefore, the light shielding pattern 660 is generally arranged corresponding to the scanning line 120 and the data line 130 so as not to adversely affect the image display quality.

  The color filter array 650 is disposed corresponding to the pixel array 104.

Specifically, as shown in FIG. 8, the angle θ <b> 2 is an acute angle formed between the dummy light shielding pattern 670 and a part of the light shielding patterns 664. However, the present invention is not limited to this. For example, the angle θ2 may be an arbitrary angle (not shown) formed between the dummy light shielding pattern 670 and a part of the light shielding patterns 666. From another viewpoint, the extending direction of the dummy light-shielding pattern 670 can form an angle θ2 with respect to the X direction or the Y direction.
