1. A liquid crystal display device, comprising:

  • a liquid crystal panel;

    a printed circuit board; and

    a tape carrier package connected to the liquid crystal panel and the printed circuit board, the tape carrier package comprising;

    a base film mounted with an integrated circuit chip for applying a signal to the liquid crystal panel;

    an output pad part extending from the integrated circuit chip and having terminals connected to the liquid crystal panel;

    a dummy bending part in which a portion of the base film is removed in a direction perpendicular to the terminals of the output pad part for reducing a thermal expansion force and a thermal contraction force generated when thermal-pressing the output pad part onto the liquid crystal panel;

    a first bending part in which a second portion of the base film existing at a bent position between the dummy bending part and the integrated circuit chip is removed; and

    an input pad part extending from the integrated circuit chip and having terminals connected to the printed circuit board, wherein the dummy bending part is formed at a position, close to any one of the output pad part or the input pad part, where the tape carrier package is not folded.
