Abstract:
A reflective liquid crystal display device includes a first substrate including a display region and a first non-display region, the first non-display region being disposed at a boundary of the display region. A second substrate faces and is spaced apart from the first substrate, the second substrate including a second non-display region corresponding to a portion larger than the first substrate. A light absorption layer is on an inner surface of the first substrate. A cholesteric liquid crystal color filter (CCF) layer is at the display region and the first non-display region is on the light absorption layer. A common electrode is on the CCF layer. An array element is on an inner surface of the second substrate. A light shielding pattern is on the array element, the light shielding pattern corresponding to the CCF layer at the first non-display region. A retardation plate and a polarizing plate are sequentially formed on the outer surface of the second substrate. A liquid crystal layer is interposed between the common electrode and the array element.
