wherein the top cover comprises a plurality of sub-covers disposed at an edge of the display unit and two sub-covers of the plurality of sub-covers overlap with each other,

wherein the receiving container comprises a first fixing part corresponding to a position that adjacent two sub-covers of the plurality of sub-covers overlap with each other, and each of the adjacent two sub-covers comprises a second fixing part coupled to the first fixing part, and

wherein each of the adjacent two sub-covers forms a partial portion of a bezel that surrounds edges of a top surface of the display unit.

2. The display apparatus of claim 1, wherein the first fixing part is provided with a fixing protrusion disposed on the receiving container and the second fixing part is provided with a fixing hole, and

wherein a position of one of the adjacent two sub-covers relative to a position of the other one of the adjacent two sub-covers is configured to be changed.

3. The display apparatus of claim 2, wherein the receiving container further comprises a bottom portion which accommodates the display unit thereon and a sidewall which is extended from the bottom portion, and

the fixing protrusion is provided on the sidewall of the receiving container.

4. The display apparatus of claim 3, wherein the fixing hole formed through one sub-cover of the adjacent two sub-covers has an elliptical shape extended in a longitudinal direction of the sidewall,

wherein a size of the elliptical shape determines a range in which the position of one of the adjacent two sub-covers changes.

5. The display apparatus of claim 3, wherein the sidewall of the receiving container comprises a first engaging hole adjacent to the fixing protrusion, one sub-cover of the adjacent two sub-covers comprises a second engaging hole corresponding to the first engaging hole, and the receiving container and the one sub-cover are coupled with each other by a coupler passing through the first engaging hole and the second engaging hole.

6. The display apparatus of claim 3, wherein the display unit comprises:

a display panel configured to display the image;

a plurality of flexible films attached to the display panel; and

a printed circuit board electrically connected with the display panel by the plurality of flexible films.

7. The display apparatus of claim 6, wherein the plurality of flexible films are bent and cover the sidewall of the receiving container,

the printed circuit board faces a rear surface of the bottom portion of the receiving container, and

the fixing protrusion is disposed between two flexible films adjacent to each other or is disposed at an outside of an outermost flexible film of the plurality of flexible films.

8. The display apparatus of claim 2, further comprising a backlight unit configured to provide a light to the display unit,

wherein the plurality of sub-covers comprises:

first and second sub-covers disposed in a short axis direction of the backlight unit; and

third and fourth sub-covers disposed in a long axis direction of the backlight unit, and

wherein two end portions of the first and second sub-covers are bent and extended in the long axis, respectively.

9. The display apparatus of claim 8, wherein the receiving container further comprises a bottom portion which accommodates the backlight unit thereon and first and second sidewalls which are extended from the bottom portion and are substantially parallel to the long axis, and

wherein the first sidewall comprises a first fixing protrusion and a second fixing protrusion and the second sidewall comprises a third fixing protrusion and a fourth fixing protrusion.

10. The display apparatus of claim 9, wherein two end portions of the third sub-cover comprise a first protruding portion and a second protruding portion which protrude toward the first and second sub-covers, respectively,

two end portions of the fourth sub-cover comprise a third protruding portion and a fourth protruding portion which protrude toward the first and second sub-covers, respectively,

the first and second protruding portions comprise first and second fixing holes coupled to the first and second fixing protrusions on the first side wall, respectively, and

the third and fourth protruding portions comprise third and fourth fixing holes coupled to the third and fourth fixing protrusions on the second wide wall, respectively.

11. The display apparatus of claim 10, wherein two end portions of the first sub-cover overlap the first protruding portion of the third sub-cover and the third protruding portion of the fourth sub-cover, respectively and comprise fifth and sixth fixing holes coupled to the first and third fixing protrusions, respectively.
