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.
Claims8
A liquid crystal display device comprising:
- opposite first and second substrates;
- and
- column spacers between the first and second substrates, wherein the column spacers formed on one of the substrates such that the height of the column spacers differ as position of the column spacers differ,
- wherein the height of the column spacers differ as the position of the column spacers differ according to the expansion ratio of the cell gap between the first and second substrates due to gravity when the display device is in a vertical position,
- wherein the column spacers with great height are positioned lower only than the column spacers with small height.
2 more elements
A liquid crystal display device comprising:
- a thin film transistor substrate and a color filter substrate boned to each other;
- and
- at least two groups of column spacers, in different areas from each other, on one of the thin film transistor substrate and the color film substrate, wherein a height and a diameter of the at least one group of the column spacers is different from those of the other group of the column spacers, wherein the group of column spacers with the greatest height and diameter is located nearer to a bottom of the liquid crystal display device and the other group of column spacers is located nearer to a top of the liquid crystal display device due to gravity when the LCD device is in a vertical position,
- wherein the group of column spacers with great height and diameter are positioned lower only than the other group of column spacers of small height and diameter.
