    Abstract: Disclosed are an LCD device and a method of manufacturing the same, in which a passivation layer and a pixel electrode are simultaneously formed by a single mask process using a half tone mask, and thus, manufacturing efficiency increases, and a defective contact due to loss of the pixel electrode can be prevented in a pad area. The LCD device includes a pad part including a pad area and a contact area. The LCD device includes a pixel pad formed in the pad area, a pixel bar formed in the contact area, and a bridge layer contacting the pixel pad with the pixel bar. The bridge layer is formed as a single layer or multi layers, and formed of one or more of a transparent conductive material and an opaque conductive material.
