1. A refrigerator comprising:
a storage chamber;
a cooler configured to supply cold into the storage chamber; and
an ice maker comprising:
a first tray having a first portion of a cell;
a second tray having a second portion of the cell, the first portion and the second portion being configured to define a space formed by the cell;
a liquid supply configured to supply a liquid to the space;
a driver that moves the second tray relative to the first tray such that the second portion of the second tray contacts the first portion of the first tray to form the space of the cell in an ice making process when the liquid in the space is phase-changed into ice, and that moves the second tray relative to the first tray such that the second portion of the second tray is spaced from the first portion of the first tray in an ice separation process to remove the ice from the first and second trays; and
a controller configured to control the cooler and the driver,
wherein the refrigerator further comprises:
a pusher including a first edge having a surface configured to press at least one of the ice, the first tray, or the second tray to separate the ice from at least one of the first tray and the second tray, a bar extending from the first edge, a second edge disposed at an end of the bar, and a guide connection section, wherein at least one of the pusher or the second tray moves to change a position of the pusher relative to the second tray, and
a guide including a slot configured to determine a movement path of the guide connection section, and
wherein the guide connection section is at different positions in a horizontal direction, respectively, when the second tray is at a liquid supply position and at an ice separation position.
