[22] Referring to FIGS. 1 and 2, the refrigerator 1 according to the present embodiment includes a main body in which a storage chamber is formed, and at least one door 30 coupled movably to the main body 10 to open/close the storage chamber. [23] Although not shown, the main body 10 includes a panel member and an inner case, wherein a heat insulator such as expanded polystyrene (EPS) is foamly filled between the panel member and the inner case.
[24] A display unit 400 displaying at least an operation state of the refrigerator 1 is provided on the door. And, the display unit 400 allows an operation condition of the refrigerator to be selected by means of a touch method by way of example.
[25] A display window 110 allowing information displayed by the display unit 400 to be shown is formed on the front surface of the door corresponding to the position of the display unit through a front surface of the door 30. The display window 110 is formed to be transparent or translucent.
[26] Manipulating parts 130 guiding a user's touch are displayed on both right and left sides based on the display window 110 of the door 30. The manipulating parts 130, which are formed in the portions corresponding to sensing units 450 (see FIG. 5) of the display unit 400, are printed or formed in a rugged shape on the front surface of the door 30 so that they can guide the positions of the sensing units 450.
[27] And, sensors constituting the sensing units 450, which are capacitance sensors, sense microcurrent generated at the time of user's touch to generate input signals. Therefore, if a user touches the manipulating parts 130, the user's manipulation is sensed in the sensing units 450.
[28] FIG. 3 is an exploded perspective view of a refrigerator door according to a first embodiment, FIG. 4 is a partial perspective view showing a structure that a display unit according to a first embodiment is mounted to a refrigerator door, and FIG. 5 is a rear perspective view of a front plate constituting a refrigerator door according to a first embodiment.

[51] The sensing part 450 receives operating signals by a user's touch as described above.
[52] The display part 430 and the sensing part 450 are mounted on the PCB board 410, and the PCT board 410 is mounted on the unit guide 470. And, the unit guide 470 is slidingly mounted on the display case 500.
[53] Guide parts 471 projected backward are formed on the rear surface of the unit guide
470. And, the guide parts 471 are formed to be vertically long and are inserted into the inner sides of the guide rails 550.
[54] Guide ribs 473 are formed on both right and left stages of the unit guide 470. The guide ribs 473 are coupled to the mounting guide 570.
[55] A cover member 350 is coupled to the upper side deco. The cover member 350 selectively covers the inserting part 331. The cover member 350 includes a shielding part 351 shielding the inserting part 331 and a mount part 353 extended to both sides of the shielding part 351 to be coupled to the upper side deco.
[56] In the present embodiment, the display unit 400 is described to be inserted into the inside of the door by penetrating through the upper side deco. However, the display unit 400 may also be inserted into the door by penetrating through a lower side deco or through the side deco 310.
[57] FIG. 6 is a cross-sectional view taken along line A-A of FIG. 2, and FIG. 7 is a cross- sectional view taken along line B-B' of FIG. 2.
[58] Referring to FIGS. 6 and 7, an assembling method of the door will be described.
[59] First, in order to assemble the door 30, the panel member 100 and the door rider 200 are prepared. And, the panel member 100 and the inner case 200 are coupled to the side deco 310.
