ABSTRACT:
A method of producing a semi-transparent type LCD panel provides an LCD panel with reflected light transmitting through a transmissive portion of a passivation layer having the same color density. The semi-transparent type LCD panel mainly comprises a transparent substrate, a first transparent conductive layer, a first alignment layer, a liquid crystal layer, a second alignment layer, a second transparent conductive layer, a color filter layer, a passivation layer, and a TFT array substrate. A reflection layer is formed on a portion of the passivation layer. The area of the passivation layer not covered with the reflection layer is etched to a certain depth. The passivation layer has two different levels of thickness so as to allow reflected transmitting lights to be of the same color density.
