Abstract
The invention provides a transflective liquid crystal display device capable of obtaining a high contrast display in a transmissive display and a reflective display. In particular, in a liquid crystal display device according to the invention, a reflective display region and a transmissive display region can be formed in one pixel region, a reflection layer is provided on an array substrate in the reflective display region, an inclined region, in which the thickness of a liquid crystal layer varies consecutively between the transmissive display region and the reflective display region, is provided between the transmissive display region and the reflective display region, an edge of the inclined region at the transmissive display region side being formed in a plane region of the reflection layer, a first color material layer is formed in the reflective display region, and a second color material layer is formed in the inclined region and the transmissive display region, the degree of coloration of the second color material layer being higher than that of the first color material layer. The first color material layer and the second color material layer may overlap each other in the p…
