PROBLEM TO BE SOLVED: To prevent out-of-focus in a display image and to eliminate the effect of a noise by suitably selecting required combination from plural dots having different effective areas and constituting a pixel becoming a display unit. SOLUTION: A first pixel is a part of one side y1 consisting of a dot px3, and a second pixel is the part of one side y2 consisting of the dot px3, two dot px2s and one dot px1, and a third pixel is the part of one side y3 consisting of one dot px3, four dot px2s and four dot px1s. The ratio of one sides of respective pixels is 2:3:4 successively from small side, and is 4:9:16 in an area ratio. In such a case, a pixels group is divisible to m pieces of the first pixels having an effective area S1 uniformly, and is divisible also to n pieces of the second pixels having the effective area S2, and the group is constituted so as to be satisfied with S1<S2, m>n, m/n≠2a (a is natural number).
