Abstract
In a transflective liquid crystal display device including a transmission display portion and a reflection display portion, a dichroic ratio of a polarizing layer contained in a reflection region is increased to enhance display performance. The liquid crystal display device includes: the transmission display portion and the reflection display portion which are formed for each pixel; a reflective layer formed in the reflection display portion; a first substrate having a principal surface opposed to a liquid crystal layer; a second substrate opposed to the first substrate via the liquid crystal layer; and a polarizing layer formed above the reflective layer via an underlying layer thereof on the principal surface of the first substrate. The polarizing layer is made of chromonic liquid crystalline molecules, and an interface between the polarizing layer and the underlying layer has one of a siloxane structure and a silazane structure.
