ABSTRACT:
Example embodiments provide a light emitting diode (LED) having improved polarization characteristics. The LED may include wire grid polarizers on and below a light emitting unit. The wire grid polarizers may be arranged at an angle to each other. Thus, because the LED may emit a light beam in a given polarization direction, an expensive component, e.g., a dual brightness enhanced film (DBEF), is not required. Thus, manufacturing costs of a backlight unit including the LED and a display apparatus including the backlight unit may be reduced.
