Abstract
A backlight module and a liquid crystal device (LCD) are disclosed. The backlight module includes a light guiding plate, a plastic frame adjacent to a lateral side of the light guiding plate, and a reflective sheet. The reflective sheet includes a first portion, a second portion, and a third portion. The first portion of the reflective sheet is arranged below a bottom of the light guiding plate and/or a bottom of the plastic frame, the second portion of the reflective sheet adheres to a lateral side of the plastic frame, and the lateral side faces away from the light guiding plate, and the third portion of the reflective sheet adheres to a top surface of the plastic frame. With such configuration, the reflective sheet may be stably fixed on the plastic frame to prevent the reflective sheet from being detached.
