Liquid crystal display device and method of fabricating the same

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.

1 . A liquid crystal display device comprising:
 (a) a first substrate;   (b) a second substrate facing and spaced away from said first substrate;   (c) a liquid crystal layer sandwiched between said first and second substrates;   (d) a switching device formed on said first substrate;   (e) an electrically insulating film formed on said first substrate, and defined by a thick region and a thin region, said electrically insulating film having a wavy surface; and   (f) a reflection electrode formed on said electrically insulating film, and electrically connected to an electrode of said switching device,   wherein a light passing through said second substrate and said liquid crystal layer is reflected at said reflection electrode,   said thin region extends inwardly from said thick region by a certain length at a contact region where said reflection electrode is electrically connected to said electrode of said switching device, such that a step formed by said electrically insulating film in the vicinity of said contact region is smoothed.   
   
   
       2 . The liquid crystal display device as set forth in  claim 1 , wherein said certain length is in the range of about 10 μm to about 12 μm both inclusive. 
   
   
       3 . The liquid crystal display device as set forth in  claim 1 , wherein said thin region has a thickness in the range of about 0.3 μm to about 1.5 μm both inclusive. 
   
   
       4 . The liquid crystal display device as set forth in  claim 1 , wherein said thick region has a thickness in the range of about 1 μm to about 3 μm both inclusive. 
   
   
       5 . The liquid crystal display device as set forth in  claim 1 , wherein said electrically insulating film is composed of thermo-flexible organic or inorganic material.
