[0031]

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1A shows spectral characteristics of a general color filter composed of three colors of RGB. As shown in the drawing, the filters of each color of RGB have a light transmittance having a mountain-shaped waveform, and have a valley between them. For example, the B filter absorbs the R and G components of the light component and transmits the B component. The transmittance is high near the peak portion of each filter, and the color corresponding to the wavelength is displayed relatively well. However, between the transmittance characteristics of each filter (the valley portion), the adjacent two-color filters As a result of the light being transmitted by both, the color is developed, and the color is poor compared to the wavelength near the peak of each filter that is colored by the transmitted light of a single filter.

Therefore, a characteristic 10 shown by a dotted line in FIG.
If filters having characteristics such as 0 and 101 that interpolate the characteristics of the three color filters are used, the spectral characteristics of the entire color filter can be reduced by compensating for the valleys in the spectral characteristics of the RGB three color filters. Characteristic can be approximated. That is, a color having a light transmission characteristic having a peak at a wavelength corresponding to a valley portion of the light transmission characteristic of each color (hereinafter referred to as “interpolated color”) is added to the existing RGB three color filters.
Also called. By adding the filter of (1), more natural coloring can be realized.

FIG. 1B shows an example of spectral characteristics of a color filter using such an interpolation color. In the example of FIG. 1B, a band of 400 nm to 700 nm is divided into six at substantially equal intervals on the wavelength spectrum, and filters of six colors (colors C1 to C6) having a peak at a substantially central wavelength of each band are used. 4 shows spectral characteristics of a color filter. As described above, if the number of colors constituting the color filter is increased and the wavelengths of the light components transmitted by the filters of the respective colors are arranged at equal intervals, the spectral characteristics of the entire color filter are flattened, and a more natural color development is achieved. Can be realized.

For example, as shown in FIG.
Is blue, color C2 is turquoise (Blue-Green), color C
3 is green (Green), color C4 is yellow-green (Yellow-Gree
n), by setting the color C5 to orange (Orange) and the color C6 to red (Red), it is possible to make the wavelengths of light transmitted by the filters of the respective colors substantially equal.

FIGS. 2A to 2C show examples of color filter arrangement patterns composed of filters of the respective colors C1 to C6. Note that the filter portions of the individual colors formed on the color filters are hereinafter referred to as “color regions”. FIG.
3A to 3C, only the arrangement of each color region is shown for convenience, and a substrate and a light-shielding layer (black mask) formed between the color regions are not shown.

FIG. 2A shows the colors C1 to C6 of this embodiment.
Are arranged in a so-called stripe arrangement. A plurality of pixels are arranged in the vertical direction in FIG. That is, in this filter arrangement, a plurality of pixels are arranged corresponding to a stripe-shaped color region in the length direction of the stripe shape.

FIG. 2 (b) shows a configuration in which the filters of the respective colors C1 to C6 of the present invention are arranged in a so-called mosaic (diagonal) arrangement. 1 for each color area of C1 to C6
One pixel is arranged to correspond. In the example of FIG. 2B, the colors C1 and C2 shown in FIG. 1B are regarded as B (blue), the colors C3 and C4 are regarded as G (green), and the color C5 is displayed.
And C6 are regarded as R (red), and the color regions of the colors C1 to C6 are configured in the conventional mosaic arrangement. As a result, the first
In the row, the second row, and the third row, each color is shifted by two colors in the horizontal direction. Instead of this configuration, for example, it is also possible to arrange the color regions of the respective colors C1 to C6 such that the colors are shifted by one color or three colors in the horizontal direction, for example. The color areas of the respective colors C1 to C6 are formed on the substrate so as to correspond to one pixel, similarly to the conventional RGB filters.

FIG. 2C shows a so-called delta (triangle) arrangement of the color regions of the respective colors C1 to C6 of the present invention. One pixel is arranged so as to correspond to the color area of each color C1 to C6. In the example of FIG. 2 (c), similarly to the example of FIG. 2 (b), the colors C1 and C2 are regarded as B, the colors C3 and C4 are regarded as G, and the colors C5 and C6 are regarded as R. Color areas of colors C1 to C6 are applied to the arrangement.

As described above, according to the first embodiment, since the plurality of colors constituting the color filter are determined so as to be located at substantially equal intervals on the wavelength spectrum, the spectral characteristics of the entire color filter are determined. Are flattened, and natural light emission is realized for various colors. In the example of FIG. 2, the color filter is configured using six colors. However, the wavelength of the valley portion of the spectral characteristics of the RGB color filter shown in FIG. Another one to penetrate
By adding colors or two colors, a total of four or five color filters can be obtained. (Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. As in the case of FIG. 2, FIGS. 3 and 4 show only the arrangement of the color regions of each color, and do not show the light-shielding film formed between the substrate and the color regions.

In the second embodiment, three color filters of Y (yellow), M (magenta) and C (cyan) are added in addition to the conventional RGB filters. Is configured. First, a basic idea in an arrangement of six color regions will be described with reference to FIGS. Regarding the RGB and YMC filters, the following rules hold for color addition: R = Y + M, G = C + Y, and B = M + C. Therefore, by adjusting the ratio of adding Y and M, a subtle color close to R can be expressed.
Similarly, a subtle color close to G can be expressed by adjusting the ratio of adding C and Y, and a subtle color close to B can be expressed by adjusting the ratio of adding M and C. Can be.

From this point of view, a filter in which the three color filters of R, Y, and M are arranged in the vertical or horizontal direction is used as a group color region 3R of the red group, and is used instead of the conventional R color region. Similarly, a three-color filter of G, C, and Y arranged in a vertical or horizontal direction is used as a group color area 3G of a green group instead of the conventional G color area, and B, M, and C are used. The three color filters arranged in the vertical or horizontal direction are used as the group color area 3B of the B group instead of the conventional B color area. Group color region 3 in which filters of three colors are arranged in the vertical direction.
Examples of R, 3G, and 3B are shown in FIG. 3A, and a group color region 3R in which filters of three colors are arranged in a horizontal direction.
FIG. 3B shows an example of 3G and 3B. Normally, a light-shielding film is formed at the boundary of each color region to prevent color mixture of adjacent colors. However, in the second embodiment of the present invention, between color regions in one group color region (for example, FIG. The light-shielding film at the boundary of the Y, R, and M color regions in the red group color region 3R of (a)) may be omitted. This is because the colors constituting one group color area are close to each other, so that it is considered that there are few defects due to color mixing.

FIG. 3C shows the above group color area 3R,
This is an example in which 3G and 3B are regarded as conventional RGB color regions and configured in a stripe arrangement. Therefore, the group color region 3R shown in FIG. 3A or 3B is arranged in the portion of the group color region 3R in FIG.

FIG. 4A shows the group color areas 3R, 3G,
FIG. 4B shows an example in which 3B is configured as a conventional RGB area and arranged in a mosaic arrangement.
This is an example in which G and 3B are regarded as conventional RGB color regions and are configured in a delta arrangement.

As described above, instead of the conventional RGB color regions, the RGB color regions are formed as three color group color regions including a plurality of color filters constituting the color.
