A mobile terminal, comprising:

• a first frame;
• a second frame configured to move with respect to the first frame in a first direction or a second direction opposite to the first direction;
• a flexible display comprising a fixed part coupled to a front side of the first frame and a variable part extended in the first direction from the fixed part, wherein an end portion of the variable part is curved toward a direction of a rear side of the mobile terminal and is configured to slide with respect to a rear side of the second frame;
• a first guide rail extended in the first direction, wherein the second frame comprises a second guide rail coupled to the first guide rail such that the second guide rail is configured to slide in the first direction with respect to the first guide rail and a rear cover covering the variable part coupled on a rear side of the second frame, the first guide rail and the second guide rail,
• a main board installed in the first frame;
• a battery installed in the second frame such that the battery moves together with the second frame;
• and
• a signal connection connecting the battery and the main board,
• wherein the signal connection comprises:
• a first connection connected to the main board,
• a second portion connected to the battery, and positioned in the first direction from the first portion, and
• a curved portion between the first portion and the second portion, and having an angle varying in response to movement of the second frame,
• wherein the first portion and the second portion are arranged overlapping in the first direction in the contracted state, and wider as the angle of the curved portion increases in the extended state.
