Zusammenfassung:	Disclosed herein is a display apparatus. The display apparatus includes a backlight unit configured to emit light, a display panel positioned in front of the backlight unit, and an optical film (100) positioned in front of the display panel. The optical film (100) includes a base layer (101) positioned adjacent to the display panel, a first refractive layer (110) positioned in front of the base layer (101) and having a pattern (111) including a first inclined portion (112) totally reflecting some of light waves emitted from the backlight unit, and a second refractive layer (120) positioned in front of the first refractive layer (110) and having a lower refractive index than the first refractive layer.
