A refrigerator comprising a cabinet, a door configured to open/close the cabinet, an outer plate defining a front surface of the door and having an opening formed therein to pass through the door, and a door liner defining a rear surface of the door, the refrigerator comprising: lighting members configured to illuminate storage spaces (12; 13) of the door and the cabinet; a transparent panel assembly mounted to shield the opening, and allowing the storage spaces (12, 13) to be selectively seen according to an ON/OFF state of the lighting members; an insulator (531; 531a) filled between the outer plate and the door liner; and a support frame (70; 170; 270) provided inside the door, the transparent panel assembly comprises a front panel (61; 61a) defining the front surface of the door, a rear panel (65; 65a) defining the rear surface of the door and a spacer (63; 66; 67) connecting the front panel (61; 61a) and the rear panel (65; 65a), wherein the support frame (70; 170; 270) comprises a plate support (74; 171; 271) fixed to a rear surface of the outer plate and a panel support (76; 172; 272) extending to an inside of the opening to support the periphery of the front panel, the support frame (70; 170; 270) further comprises: a blocking part (77; 173; 273; 516; 563) arranged inside the door along a periphery of the transparent panel assembly, and detachably coupled to a peripheral surface of the transparent panel assembly to fix the transparent panel assembly, and the blocking part (77; 173; 273; 516; 563) extends from the panel support (76; 172; 272) to the door liner, and prevents foam liquid injected to form the insulator (531; 531a) from permeating toward the peripheral surface of the transparent panel assembly. lighting members configured to illuminate storage spaces (12; 13) of the door and the cabinet; a transparent panel assembly mounted to shield the opening, and allowing the storage spaces (12, 13) to be selectively seen according to an ON/OFF state of the lighting members; an insulator (531; 531a) filled between the outer plate and the door liner; and a support frame (70; 170; 270) provided inside the door, the transparent panel assembly comprises a front panel (61; 61a) defining the front surface of the door, a rear panel (65; 65a) defining the rear surface of the door and a spacer (63; 66; 67) connecting the front panel (61; 61a) and the rear panel (65; 65a), wherein the support frame (70; 170; 270) comprises a plate support (74; 171; 271) fixed to a rear surface of the outer plate and a panel support (76; 172; 272) extending to an inside of the opening to support the periphery of the front panel, the support frame (70; 170; 270) further comprises: a blocking part (77; 173; 273; 516; 563) arranged inside the door along a periphery of the transparent panel assembly, and detachably coupled to a peripheral surface of the transparent panel assembly to fix the transparent panel assembly, and the blocking part (77; 173; 273; 516; 563) extends from the panel support (76; 172; 272) to the door liner, and prevents foam liquid injected to form the insulator (531; 531a) from permeating toward the peripheral surface of the transparent panel assembly. a blocking part (77; 173; 273; 516; 563) arranged inside the door along a periphery of the transparent panel assembly, and detachably coupled to a peripheral surface of the transparent panel assembly to fix the transparent panel assembly, and the blocking part (77; 173; 273; 516; 563) extends from the panel support (76; 172; 272) to the door liner, and prevents foam liquid injected to form the insulator (531; 531a) from permeating toward the peripheral surface of the transparent panel assembly.
