DISPLAY DEVICE
FIG2 is a cross-sectional view taken along line I-I' of FIG1
The support frame 400 is fastened to the bottom case 600 to support the display panel 100 and the top case 500. In addition, the support frame 400 maintains an interval between the display panel 100 and the optical sheet 200 to be substantially constant. To this end, as illustrated in FIG2, the support frame 400 may have an overall quadrangular frame shape including a first support portion 411a, a second support portion 411b, and a fastening portion 411c. These portions may be disposed at all sides of the display device in the top plan view, without being limited thereto.
