Abstract
A liquid crystal display is provided which has improved wide angle viewing characteristics. The liquid crystal display includes a liquid crystal matrix. A non-planar fluorescent lamp positioned on a first side of the liquid crystal matrix has a center which traverses the fluorescent lamp in at least one longitudinal direction. A distance between the first side of the liquid crystal matrix and the fluorescent lamp center in a first portion of the fluorescent lamp is less than a distance between the first side of the liquid crystal matrix and the fluorescent lamp center in a second portion of the fluorescent lamp.
