1. A laundry treating apparatus comprising:
a tub configured to receive washing water;
a drum disposed in the tub and configured to receive laundry, the drum being configured to rotate about a rotation axis that extends in a front-rear direction of the tub; and
a plurality of lifters disposed on an inner circumferential surface of the drum and configured to rotate about the rotation axis based on rotation of the drum, the plurality of lifters comprising:
a plurality of front lifters disposed at a front portion of the drum and arranged along a circumferential direction of the drum, and
a plurality of rear lifters disposed at a rear portion of the drum and arranged along the circumferential direction of the drum,
wherein the plurality of front lifters and the plurality of rear lifters define a plurality of groups of lifters, each group having a pair of lifters including a front lifter among the plurality of front lifters and a rear lifter among the plurality of rear lifters,
wherein respective central longitudinal axes of the front lifter and the rear lifter in each group of the plurality of groups of lifters are spaced apart from each other in the circumferential direction to thereby define a phase angle between the front lifter and the rear lifter in each group of the plurality of groups of lifters about the rotation axis, and
wherein the front lifter and the rear lifter in each group of the plurality of groups of lifters overlap with each other along the front-rear direction.
