Reflection type liquid crystal display device with a passivation layer directly on the pad electrode

摘要

Disclosed are a reflection type LCD and method of manufacturing the same. A wiring layer having a first and second metal layer ( 102, 104 ) is formed on a substrate ( 100 ) including a display region (D) and a pad region (P). Upon the substrate ( 100 ) and the wiring layer is formed a first passivation layer ( 155 ), and contacts with a wiring terminal ( 115 ) and the first metal layer ( 102 ). A second passivation layer ( 180 ) is formed on the substrate except the pad region (P). The pad contact hole ( 160 ) extends to a position under the second passivation layer ( 180 ). The second passivation layer ( 180 ) covers a region in the pad contact hole ( 160 ) where the step coverage of the pad electrode ( 170 ) is poor, thereby preventing a battery effect.
