Each voltage holding section Hk,n can receive and hold a voltage outpout from any one pixel selected from M pixels P1,n-PM,n in the n-th column out of the M×N pixels Pm,n and can outputs the voltage thus holding.

The pixel in the n-th row and the pixel in the (n 1)-th row are in an identical column.

In formula (I) R, Z, Z', W, n, n' and m are as defined in the application.

In some embodiments, the N- acyl-N,N',N'-alkylenediamine trialkanoic acid ester is a synthetic intermediate in the preparation of a N-acyl-N,N',N'-alkylenediamine trialkanoic acid or a salt thereof.
