Abstract
A front light () and a reflecting liquid crystal display of the present invention includes a dot light emitting source (), and a light guiding body () having a light incident surface () to which light from the dot light emitting source () is incident and a light outgoing surface () from which the incident light outgoes, and light from the dot light emitting source () is in a linearly emitting state at least when incident onto the light incident surface (). By so doing, it is possible to provide bright, inexpensive, low-power consuming front light () and reflecting liquid crystal display which do not cause shadows or a moire fringe from the dot light emitting source (), or a light-dark difference in luminance.
