ABSTRACT:
A liquid crystal display device including opposite first and second substrates, and column spacers between the first and second substrates, the column spacers formed such that the column spacers differ in size as positions of the column spacers differ, thereby accommodating the variation in gap between substrates when liquid crystal is concentrated at a lower end of the display due to gravity when a large LCD panel is in a vertical position.
