摘要： Provided is a liquid crystal display device with a backlight including a light guide plate. The light guide plate includes, a reflective polarizing plate for transmitting a P-polarized component and reflecting an S-polarized component, a reflector for reflecting the S-polarized component reflected by the reflective polarizing plate, and a polarization converting member for converting the S-polarized component to a P-polarized component. The reflective polarizing plate and the reflector are tilted at an angle such that reflecting surfaces thereof are not perpendicular to four sides of the liquid crystal display panel and are disposed such that the S-polarized component contained in a main component of light emitted from the light sources is reflected by the reflector. This keeps small the size of the liquid crystal display device and still improves reuse efficiency of the light emitted from the light sources.
