The flexible display unit can include a display panel, a first member on a rear surface of the display panel, and a second member between the display panel and the first member. The flexible display unit can implement a first state by moving the first frame in a first direction with respect to the second frame, or can implement a second state by moving the first frame in a second direction being different from the first direction. ## Claims ### Claim 1 A display apparatus, comprising: a first frame, a second frame, and a third frame forming an outer periphery; and a flexible display unit including a first area coupled to the first frame, a second area coupled to the third frame, and a third area located between the first area and the second area, wherein the flexible display unit includes: a display panel; a first member on a rear surface of the display panel, and including a groove portion extending in a first direction; a second member between the display panel and the first member; and a third member accommodated in the groove portion, and wherein the flexible display unit implements a first state by moving the first frame in the first direction with respect to the second frame or implements a second state by moving the first frame in a second direction being different from the first direction, wherein the first member includes: a rib portion having a plurality of ribs disposed to be perpendicular to the first direction; a first flat portion at one side of the rib portion; and a second flat portion at another side of the rib portion, and wherein the groove portion is disposed over a part of the first flat portion, the entire rib portion, and a part of the second flat portion. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein the second member includes: a 2-1-th member adjacent to the display panel; and a 2-2-th member adjacent to the first member. ### Claim 3 (depends on 2) The display apparatus according to claim 2, further comprising: a first adhesive layer between the display panel and the 2-1-th member; and a second adhesive layer between the 2-2-th member and the first member. ### Claim 4 (depends on 2) The display apparatus according to claim 2, wherein the 2-2-th member includes a pattern unit corresponding to the rib portion of the first member. ### Claim 5 (depends on 1) The display apparatus according to claim 1, wherein the third member is disposed between the first member and the second member. ### Claim 6 (depends on 1) The display apparatus according to claim 1, further comprising: a fixing unit in an overlapping position of the third member and the second flat portion, wherein one side of the third member is fixed between the first flat portion and the second member, and another side of the third member is fixed between the second flat portion and the fixing unit. ### Claim 7 (depends on 3) The display apparatus according to claim 3, wherein each of the first adhesive layer and the second adhesive layer includes an optically clear adhesive film. ### Claim 8 (depends on 3) The display apparatus according to claim 3, further comprising: a third adhesive layer disposed between the 2-1-th member and the 2-2-th member. ### Claim 9 (depends on 1) The display apparatus according to claim 1, further comprising: a roller which is disposed at an end portion of the second direction in the second frame and abuts onto an inner surface of the flexible display unit. ### Claim 10 (depends on 9) The display apparatus according to claim 9, wherein the second frame includes a side frame to protect the flexible display unit wound around the roller. ### Claim 11 (depends on 1) The display apparatus according to claim 1, wherein a length of the groove portion is longer than that of the third area and shorter than that of the flexible display unit. ### Claim 12 (depends on 1) The display apparatus according to claim 1, wherein a width of the third member is smaller than a width of the groove portion, and a length of the third member is larger than a length of the groove portion. ### Claim 13 A display apparatus, comprising: a display panel configured to display an image; a first member on a rear surface of the display panel and including a groove portion having a top surface partially removed in one direction; a second member between the display panel and the first member; a third member accommodated in the groove portion; and a fixing unit in an overlapping position of the third member, wherein the first member includes: a rib portion having a plurality of ribs disposed in a direction perpendicular to the one direction; a first flat portion disposed at one side of the rib portion; and a second flat portion disposed at another side different from the one side of the rib portion, and wherein one side of the third member is fixed between the first flat portion and the second member, and another side of the third member is fixed between the second flat portion and the fixing unit. ### Claim 14 (depends on 13) The display apparatus according to claim 13, further comprising: a first adhesive layer between the display panel and the second member; and a second adhesive layer between the second member and the first member. ### Claim 15 (depends on 14) The display apparatus according to claim 14, wherein the second adhesive layer is not disposed in the groove portion. ### Claim 16 (depends on 13) The display apparatus according to claim 13, wherein the second member includes a pattern unit corresponding to the rib portion of the first member. ### Claim 17 (depends on 13) The display apparatus according to claim 13, wherein the groove portion is disposed over a part of the first flat portion, the entire rib portion, and a part of the second flat portion. ### Claim 18 (depends on 13) The display apparatus according to claim 13, wherein the display panel, the first member, the second member, and the third member constitute a display unit, and wherein the display unit slidably moves in the one direction or another direction through a roller. ### Claim 19 (depends on 13) The display apparatus according to claim 13, wherein a width of the third member is smaller than a width of the groove portion, and a length of the third member is larger than a length of the groove portion.
