Lighting device, and electronic device using the same
First Claim
1. A lighting device, comprising:
- an organic electroluminescent element; and
a transparent substrate, said substrate having a first principal plane on which light from said organic electroluminescent element is incident and a second principal plane, the light incident on said substrate comprising a first light emitted from the second principal plane of said substrate, and a second light emitted from a third plane different from the first principal plane and the second principal plane, the first light illuminating a first object and the second light illuminating a second object different from the first object.

Abstract
A composite lighting device is provided, which is inexpensive and has high uniformity in brightness, in which light emitted from an end face of a backlight having an organic EL device is used to illuminate input buttons and the like. The lighting device includes a transparent substrate having one principal plane on which a transparent electrode film, a luminescent layer, and a reflective electrode film are at least formed. In the lighting device, a liquid crystal display unit is adjacently disposed on the other principal plane, and a light-guide element is adjacent to an end face of the substrate, so that input buttons embedded into the light-guide element are illuminated.
