Abstract
A light emitting layer containing a fluorescent material is provided on the back surface of a liquid crystal panel. External light transmitted by the liquid crystal panel and incident on the light emitting layer causes the light emitting layer to emit light to illuminate the back surface of the liquid crystal panel. Moreover, the light emitting layer is formed as an anisotropic conductive light emitting layer in which the current flow is allowed only along the thickness of the anisotropic conductive light emitting layer. An electronic part for driving liquid crystal is mounted on the anisotropic conductive light emitting layer and connected to the electrodes of the liquid crystal panel through the anisotropic conductive light emitting layer.
