Abstract
An LCD and method are provided in which a cell gap between substrates is maintained and an overcharge of liquid crystal is prevented. In the LCD, a first substrate includes a TFT and a color filter layer and a second substrate faces the first substrate. A column spacer is formed on the first substrate and a protrusion is formed on the second substrate at a position corresponding to the column spacer. And, a liquid crystal layer is formed between the first and second substrates.
