Abstract
A liquid crystal display device including a first substrate, a second substrate facing and spaced away from the first substrate, a liquid crystal layer sandwiched between the first and second substrates, a switching device formed on the first substrate, a first electrically insulating film randomly patterned on the first substrate, a second electrically insulating film covering the first electrically insulating film therewith, and having a wavy surface, and a reflection electrode formed on the second electrically insulating film, and electrically connected to an electrode of the switching device, wherein a light passing through the second substrate and the liquid crystal layer is reflected at the reflection electrode, and the second electrically insulating film extends outwardly from the first electrically insulating film by a certain length at an end of a display region in which images are to be displayed, such that a step formed by the first and second electrically insulating films in the vicinity of the end of the display region is smoothed.
