Abstract
A bottom chassis includes a base chassis which accommodates a light source part emitting a light, a reflective film disposed on a bottom plate of the base chassis and including a reflective material to reflect the light, a cladding film disposed on the reflective film, and a light guide film disposed on the cladding film, receiving the light from the light source part through a first surface thereof, and guiding the received light to exit through a second surface thereof as a plane light, where the cladding film has a refractive index smaller than a refractive index of the light guide film.
Claims20
A bottom chassis comprising:
- a base chassis which accommodates a light source part which emits a light;
- a reflective film which is disposed on a bottom plate of the base chassis and includes a reflective material to reflect the light;
- a cladding film disposed on the reflective film;
- and
- a light guide film which is disposed on the cladding film, receives the light from the light source part through a first surface thereof, and guides the received light to exit through a second surface thereof as a plane light,
- wherein the cladding film has a refractive index smaller than a refractive index of the light guide film.
A method of manufacturing a bottom chassis, the method comprising:
- forming a base chassis;
- providing a reflective material on a bottom surface of the base chassis to form a reflective film;
- providing a cladding material on an upper surface of the reflective film to form a cladding film;
- and
- providing a guiding material on an upper surface of the cladding film to form a light guide film, wherein the cladding material has a refractive index smaller than a refractive index of the guiding material.
A display apparatus comprising:
- a light source part which emits a light;
- a bottom chassis which receives the light from the light source part, converts the light to a plane light and comprises:
- a base chassis which accommodates the light source part;
- a reflective film disposed on a bottom plate of the base chassis and including a reflective material to reflect the light;
- a cladding film disposed on the reflective film;
- and
- a light guide film which is disposed on the cladding film, receives the light from the light source part through a first surface thereof, and guides the received light to exit through a second surface thereof, and
- a display panel which receives the plane light from the bottom chassis to display an image,
- wherein the cladding film has a refractive index smaller than a refractive index of the light guide film.
