Abstract
A liquid crystal display apparatus includes a liquid crystal panel in which a liquid crystal layer is interposed between a pair of substrates, a front light unit that illuminates the liquid crystal panel, and a cell case that cooperates with the front light unit to sandwich the liquid crystal panel. The front light unit comprises a light source section, a plate-shaped light guide body that guides light from the light source section to the liquid crystal panel, and a frame-shaped protection member mounted on a peripheral portion of the light guide body and engaged with the cell case, thus integrally holding the liquid crystal panel and the light guide body.
