Have a look this chromatic diagram, because with respect to R ', G ', B ' area as the color triangle on summit, the tetragonal area of the look that R, G, B, C were enclosed with present embodiment is bigger, so as can be known: the color reproduction scope that the transmission of present embodiment shows is wideer than the color reproduction scope that reflection shows.And, as can be known, constituting under the situation of carrying out the transmission demonstration with existing trichromatic color filter, though as R ', G ", have wide to a certain degree color reproduction scope shown in the color triangle of B ', the color reproduction scope that is obtained by R, G, B, the C of present embodiment can be for equating with it or being the wide region greater than it.
In the present embodiment, not only in transmission shows, can realize wide color reproduction scope, but also can realize that bright reflection shows with the dyed layer of three looks of the R, the G that are disposed at reflection region Ar, B with the dyed layer of four looks of the R, the G that are disposed at light transmission region At, B, C.Promptly, even reducing under the situation of the formation that realizes that bright reflection shows for the chroma that is suitable for use in three looks that make basic R, G, B, also because in transmission shows so that above-mentioned three looks have been added four looks of C and can show colour, so can suppress the reduction of the color reproduction that transmission shows.In addition, under this situation, because needn't change the dyed layer 122at that is disposed at light transmission region At and reflection region Ar and the chroma of 122ar, so can reduce the worker ordinal number of color filter, needn't make manufacturing process complicated so have, also can suppress the advantage of the rising of manufacturing cost.
The dyed layer 122at of sub-pixel Dxc also can adopt the coloured material of other colors except that above-mentioned viridescent and forms.But, preferred: as to have by being added to the three basic looks of red, green, blue, and make the tone of color reproduction expanded range.Preferably: for example, have the tone of on chromatic diagram, separating fully with other three looks, and, have high to a certain degree chroma, that is, have the tone in the outside that on chromatic diagram, is positioned at by other three looks formed color triangle.Most preferably be the color of complementary color system as such look, for example, dark green, aubergine or yellow etc.
In addition, though a sub-pixel Dxc only is set in the present embodiment, also a plurality of sub-pixels that append can be set beyond three sub pixels in pixel Px beyond three sub pixels.For example, also can be in pixel Px, setting has the sub-pixel Dxc of dark green dyed layer and has the sub-pixel of two kinds of the sub-pixel Dxm of mauve dyed layer (not shown go out), and these sub-pixels are similarly constituted with the sub-pixel Dxc of above-mentioned embodiment respectively.Becoming a pixel Px thus constitutes by five sub pixels.
Also have, in the present embodiment, by side by side form the dyed layer 122at that is disposed at light transmission region At with same material, suppress the rising of manufacturing cost with the dyed layer 122ar that is disposed at reflection region Ar, and in order to improve the color reproduction that transmission shows more, and, guarantee to reflect the brightness of demonstration more fully, and one side covers and disposes chroma than higher dyed layer on whole property ground of light transmission region At, disposes identical dyed layer on reflection region Ar part ground (optionally) on the other hand.That is, the zone that does not dispose dyed layer and expose reflection horizon 116 is set at reflection region Ar.Thus, even it is a lot of that the chroma of dyed layer itself is reduced, also can obtain and make the same effect of situation of the chroma reduction of dyed layer 122ar in reflection region Ar integral body.But, also can at least a sub-pixel among these three sub pixels, form dyed layer 122ar on whole property ground of reflection region Ar.
And, because the whole light transmission region of present embodiment to each other, reflection region has separately area identical mutually to each other, so can show and reflection shows easily carries out the colored control that shows in separately in transmission.And,,, can suppress the reduction of display resolution therefrom so can suppress the Magnification of the area of pixel Px because light transmission region At only is set at sub-pixel Dxc.
And then, in present embodiment, because dispose the regional transmission file part of light transmission region At of the dyed layer 122at of four looks, on the area arrangement direction, has equal length with the reflector space file part of the reflection region Ar that disposes tricolored dyed layer 122ar, so can make pixel Px is simple plane shapes such as rectangle, thus, be easy to make pixel Px seamlessly to arrange.And, because in the length range of same area orientation, partly dispose the zone of four looks in the regional transmission file, partly dispose the zone of three looks in the reflector space file, so it is bigger than the mean value of the width of the area arrangement direction of light transmission region At that the mean value of the width of the area arrangement direction of each reflection region Ar becomes, so the advantage that the area of reflection region is increased.
In addition, in present embodiment, as above-mentioned ground, as shared look, and the viridescent that adopts complementary color system is as only being set in the look of transmission in showing at transmission shows and former colour system is adopted in reflection in showing three looks of red, green, blue, thus, though especially, can broadening the color reproduction of hue regions of green system, in this case, obtain greatly by poor (distance on the chromatic diagram) with green and dark green spectrum colour, can improve color reproduction more.For example, in Fig. 6, with the tone point G of green look as than existing look G ', G " leave the tone of dark green tone point C, thus, set to such an extent that can increase the area of color triangle, the color reproduction scope is further increased.
