As shown in Figure 14 to Figure 16, mean be when conductive grid when the projection of filter layer 240 does not drop on gridline, the projection of each described conductive grid on described filter layer 240 of the first conductive layer 230 and/or described the second conductive layer 260 accommodates the filter unit of at least two.Now also can be divided into three kinds of situations, take is laterally X-axis, and the direction of vertical transverse is Y-axis.As shown in figure 14, only, on X-direction, at least two integers filter unit is held in the projection of each conductive grid on filter layer 240 of the first conductive layer 230 and the second conductive layer 260.As shown in figure 15, only, on Y direction, at least two integers filter unit is held in the projection of each conductive grid on filter layer 240 of the first conductive layer 230 and the second conductive layer 260.As shown in figure 16, on X-axis and Y direction, at least two integers filter unit is held in the projection of each conductive grid on filter layer 240 of the first conductive layer 230 and the second conductive layer 260 simultaneously.
In the present embodiment, the filter unit number that the filter unit number that the projection of each conductive grid on filter layer 240 of the first conductive layer 230 held holds with the projection of each conductive grid on filter layer of the second conductive layer 260 can be not identical.Can effectively reduce manufacture difficulty.Certainly, in other embodiment, the filter unit number that the filter unit number that the projection of each conductive grid on filter layer 240 of the first conductive layer 230 held holds with the projection of each conductive grid on filter layer of the second conductive layer 260 can also be identical.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
