Abstract
A liquid crystal display device minimizing touch inferiority and a press inferiority defects is provided. The device includes first and second substrates, a liquid crystal layer interposed therebetween, gap spacers between the first and second substrates for maintaining a cell gap, and pressure spacers between the first and second substrates configured to contact the first and second substrates when pressure is applied to the first or second substrate, wherein a spatial density of the gap spacers or a spatial density of the pressure spacers varies at different positions across the first and second substrates.
Claims41
A liquid crystal display device comprising;
- first and second substrates;
- a liquid crystal layer between the first and second substrates;
- column spacers between the first and second substrates to maintain a cell gap;
- and
- protrusions contacting corresponding column spacers, wherein a spatial number density of the protrusions varies at different positions across the first or second substrates.
A liquid crystal display device comprising:
- first column spacers contacting first and second substrates;
- and
- second column spacers on one of the first and second substrates and spaced apart from the other of the first and second substrates, wherein a spatial number density of the first column spacers varies across the first and second substrates, such that the spatial number density in a center portion is less than an outer periphery portion.
A liquid crystal display device comprising:
- first and second substrates;
- a plurality of pixels in the first and second substrates;
- a plurality of first column spacers on the second substrate, the first column spacers contacting first and second substrates;
- a plurality of second column spacers second substrates;
- and
- a plurality of protrusion on the first substrate, the protrusions being contacted with the second column spacers;
- wherein the number of the protrusions in the plurality of pixels varies across the first and second substrates, such that the number of protrusions in the pixels in a center portion of the display is less than the number of protrusions in the pixels in a periphery portion.
A liquid crystal display device comprising;
- first and second substrates;
- a liquid crystal layer between the first and second substrates;
- column spacers on the second substrate to maintain a cell gap between the first and second substrates;
- and
- protrusions on the first substrate, the protrusions contacting a part of the column spacers,
- wherein the distance between the protrusions increases in a direction from a periphery of the display toward a center of the first or second substrates.
A method for making a liquid crystal display device comprising:
- forming first and second substrates;
- forming column spacers between the first and second substrates to maintain a cell gap;
- forming protrusions contacting corresponding column spacers,
- wherein a spatial number density of the protrusions varies at different positions across the first or second substrates;
