A trifunctional (meth)acrylate compound represented by the following general formula (I); and a polymerizable composition containing the compound. The compound preferably is a compound in which ring A1, ring A
2
, and ring A
3
in general formula (I) each is a benzene ring or naphthalene ring and at least one of the ring A
1
, ring A
2
, and ring A
3
is a naphthalene ring, or is a compound in which X
1
, X
2
, and X
3
each is —COO— or —OCO—. More preferred is a compound in which ring A
3
is a naphthalene ring. Even more preferred is the compound which by itself can retain a liquid-crystal phase at 30° C. and lower temperatures. (In the formula, M
1
, M
2
, and M
3
each represents methyl, etc.; rings A
1
, A
2
, and A
3
each represents a benzene ring, naphthalene ring, etc.; Z
1
, Z
2
, and Z
3
each represents C
1-6
alkyl, etc.; X
1
, X
2
, and X
3
each represents —COO—, —OCO—, etc.; Y
1
and Y
2
each represents -L
1
-, and Y
3
represents -L
2
-, etc. (L
1
and L
2
each represents C
1-8
alkylene); a, b, and c indicate the number of substituents of the ring A
1
, ring A
2
, and ring A
3
, respectively, and when the number of six-membered rings contained in each substituted monocycle or fused ring is expressed by u, then the a, b, and c each independently is an integer of 2u+2 or smaller, provided that at least one of the a, b, and c is an integer of 1 or larger; p's each independently is an integer of 1-8; q and r each independently is an integer of 1-3; and s and t each independently is 0 or 1, provided that s+t≧1.)
