the flange portion comprises

a first di-cut portion on a first side surface of the flange portion and a second di-cut portion on a second side surface of the flange portion,

arc portions connecting the first di-cut portion and the second di-cut portion, and

first evasion portions between the first di-cut portion and the arc portions, and second evasion portions between the second di-cut portion and the arc portions, and

a distance between each of the evasion portions and an optical axis of the lens is smaller than a distance between respective opposite ends of the arc portions and the optical axis.

10. The lens assembly of claim 9 , wherein when a straight line passing through the optical axis of the lens and extending to be parallel to the first di-cut portion and the second di-cut portion is a first reference line, a shortest distance between the first reference line and any one of the first di-cut portion and the second di-cut portion is smaller than or equal to a shortest distance between the first reference line and an end of one side of the arc portions.

11. The lens assembly of claim 9 , wherein when a straight line passing through the optical axis of the lens and extending to be parallel to the first di-cut portion and the second di-cut portion is a first reference line, a shortest distance between the first reference line and any one of the first di-cut portion and the second di-cut portion is greater than a shortest distance between the first reference line and each of the evasion portions.

12. A lens assembly comprising:

a lens; and

a lens barrel configured to accommodate the lens,

wherein the lens comprises a first di-cut portion on a first side surface of the lens, a second di-cut portion on a second side surface of the lens opposing the first side surface, a first arc portion connecting first ends of the first di-cut portion and the second di-cut portion, a second arc portion connecting second ends of the first di-cut portion and the second di-cut portion, a first evasion portion between the first di-cut portion and first the arc portion, and a second evasion portion between the second di-cut portion and the second arc portion, and
