Abstract
A liquid crystal display device (LCD) and a method for manufacturing the same are shown. The LCD includes a first substrate (41), a second substrate (42) opposite to the first substrate and a liquid crystal layer (43) between the first substrate, and the second substrate. A number of photospacers (44) are arranged on the first substrate and a conductive layer covers (440) on the photospacers. A number of common lines (421) are arranged on the second substrate and the conductive layer covered on the photospacers interconnects with the common lines electrically.
Claims15
A liquid crystal display device, comprising:
- a first substrate;
- a second substrate opposite to the first substrate;
- and
- a liquid crystal layer sandwiched between the first substrate and the second substrate;
- wherein a plurality of photospacers are positioned at an inside of the first substrate, each photospacer is partially covered by a first transparent conductive layer, a plurality of common lines are provided at the second substrate, and the photospacers extend toward the second substrate whereby the first transparent conductive layers are electrically connected with the common lines.
A method for manufacturing a liquid crystal display device, including the steps of:
- providing a first substrate and a second substrate;
- positioning a color filter and a black matrix at an inside of the first substrate;
- forming a first protective layer on the color filter and the black matrix;
- forming a plurality of photospacers on the first protective layer;
- forming a first transparent conductive layer on exposed portions of the photospacers;
- forming a plurality of common lines at the second substrate;
- forming an isolation layer on the common lines, the isolation layer having a plurality of contact holes corresponding to the photospacers;
- positioning an alignment film on the second substrate including the above-mentioned structure;
- attaching the first substrate to the second substrate such that the photospacers substantially penetrate the alignment film whereby the first transparent conductive layers of the photospacers are in electrical contact with the common lines;
- and
- filling liquid crystal into a space between the first substrate and the second substrate whereby a liquid crystal layer is formed.
A liquid crystal display device, comprising:
- a first substrate;
- a second substrate spaced from and opposite to the first substrate;
- a first conductive layer applied upon the first substrate facing toward the second substrate;
- a second conductive layer applied upon the second substrate facing toward the first substrate;
- a liquid crystal layer sandwiched between the first substrate and the second substrate;
- and
- a plurality of photospacers are positioned between the first substrate and the second substrate;
- wherein
- at least one of said first and second conducive layer extend toward and reach the other so as to form a closed receiving sapce receiving said photospacers therein and isolating said photospacers from the liquid crystal layer.
