摘要： A front light (100) and a reflecting liquid crystal display of the present invention includes a dot light emitting source (101), and a light guiding body (104) having a light incident surface (104a) to which light from the dot light emitting source (101) is incident and a light outgoing surface (104b) from which the incident light outgoes, and light from the dot light emitting source (101) is in a linearly emitting state at least when incident onto the light incident surface (104a). By so doing, it is possible to provide bright, inexpensive, low-power consuming front light (100) and reflecting liquid crystal display which do not cause shadows or a moire fringe from the dot light emitting source (101), or a light-dark difference in luminance.

摘要： A liquid crystal display apparatus includes: an illumination section having a light source and an optical guide member, and a reflection type LCD having a display region including a plurality of pixels for performing a display function, the optical guide member having first and second principal faces opposite to each other and first and second end faces opposite to each other. The reflection type LCD is disposed on or above the first principal face of the optical guide member. Light from the light source enters the optical guide member at the first end face, exits the optical guide member at the first principal face so as to be incident on the reflection type LCD and reflected therefrom, reenters the optical guide member at the first principal face, and exits the optical guide member at the second principal face toward a viewer.

摘要： Adhesive layers are formed on the two opposing surfaces of a transparent support. At least one of the adhesive layers is made of a material of which the cured state changes by application of external force, such as a photocurable resin. A separator on the adhesive layer is peeled off, and the adhesive layer is irradiated with light. A lens sheet is then pressed against the adhesive layer. The adhesive layer is cured to a degree of hardness with which the adhesion state between lens sheet and the adhesive layer no more changes. In this way, a laminate film of the lens sheet fixed to the transparent support via the adhesive layer is obtained. The laminate film is bonded to a polarizing plate on the viewer's side of a liquid crystal display element via the other adhesive layer.
