Claim 0:
1. A backlight component, comprising:
a light guide plate;
a light emitting device on a side of the light guide plate in a thickness direction, wherein the light emitting device is configured to emit light irradiated into the light guide plate; and
an optical element on a light emitting side of the light emitting device in a thickness direction, wherein the optical element is configured to convert the light emitted from the light emitting device into a parallel beam propagating in the light guide plate by total reflection, wherein the backlight component further comprises: a filling layer on both sides of the light guide plate in the thickness direction,
wherein a material of the light guide plate and a material of the filling layer meet at least one of the following conditions:
a material refractive index of the light guide plate is greater than a material refractive index of the filling layer, and both the light guide plate and the filling layer include transparent material.
