ABSTRACT:
A liquid crystal display and a simple method to fabricate the same are provided, which can accurately measure luminance of an external light. The liquid crystal display includes a substrate; a thin film transistor array formed on the substrate; and a photoelectric conversion element having a reflection pattern formed on at least one side of the substrate, a photoelectric conversion region provided with a first semiconductor region formed on an upper part of the reflection pattern to receive an external light reflected by the reflection pattern, and a dummy pattern formed on an upper part of the photoelectric conversion region with a width corresponding to the first semiconductor region. The photoelectric conversion region may be configured to adjust the quantity of light incident to the thin film transistor array.
