Each of color element groups comprises a first color element, a second color element, a third color element and a fourth color element arranged in sequence. The first color element, the second color element, and the third color element comprising three colors. The second color element and the fourth color element are identical in color and width. An active width W1 of the first color element and an active width W2 of the second color element satisfy the formula: W1=A×W2, A=1.7˜2.3. An active width W3 of the third color element and the active width W2 of the second color element satisfy the formula; W3=B×W2, B=1.7˜2.3.
