Disclosed are LCD devices with improved display quality and front luminance and a method of manufacturing these LCD devices. Signal lines for transmitting the driving signals and TFTs are formed on the transparent substrate, and a dielectric layer is deposited on the transparent substrate. A leakage current prevention pattern is formed on a first region of the dielectric layer that overlies signal lines and the TFTs. A luminance-increasing pattern is formed on a second region of the dielectric layer that is separate from the first region. The thickness of the dielectric layer is higher at the leakage current prevention pattern than the luminance-increasing pattern, on the average. The leakage current prevention pattern has protrusions (e.g., convex portions or polygonal cones) of different dimensions. Accordingly, the leakage current can be prevented and the luminance of the LCD device can be improved.
