Array substrate for LCD device
View Patent ↗An array substrate for a liquid crystal display (LCD) device. An exemplary embodiment of an array substrate comprises a transparent substrate. A plurality of first and second conductive lines overlies the transparent substrate and cross over each other, thereby defining a plurality of display regions. At least one first spacer overlies a portion of the first or second conductive lines, wherein the first spacer is not formed over an intersection of the first and second conductive lines. A pixel electrode layer overlies the display regions, wherein the first spacer partially covers the pixel electrode layer.
1. A method for assembling a liquid crystal display (LCD) device, comprising:
providing an array substrate, comprising:
a first transparent substrate;
a plurality of first and second conductive lines overlying the first transparent substrate, crossing over each other, defining a plurality of display regions;
a pixel electrode layer overlying the first transparent substrate within each of the display regions; and
at least one first spacer overlying a portion of the first or second conductive lines, wherein the first spacer is not formed over an intersection of the first and second conductive lines, and the first spacer crosses over two of the display regions adjacent thereto and physically contacts with a part of the pixel electrode in the two of the display regions adjacent to the first spacer;
providing a color filter substrate, comprising:
a second transparent substrate;
a black matrix layer overlying the second transparent substrate, defining a plurality of light-transmitting regions; and
a color filter layer overlying the second transparent substrate in the light-transmitting regions, partially covering the black matrix layer to thereby form a recess portion between two adjacent light-transmitting regions;
aligning the first spacer with the recess portion; and
pressing the array substrate with the color filter substrate, making the first spacer support the recess portion and aligning the display regions with the light-transmitting regions, wherein the black matrix layer exposed by the recess portion physically contacts with the first spacer.
2. The method as claimed in claim 1 , before the step of pressing the array substrate with the color filter substrate, further comprising a step of filling the display regions with a liquid crystal material in.
3. The method as claimed in claim 1 , further comprising at least one second spacer overlying the first or second conductive lines not formed with the first spacer thereon, the second spacer supports the recess portion in the step of pressing the array substrate with the color filter substrate.
4. The method as claimed in claim 1 , wherein the first spacer is inserted in the recess portion and movement of the array substrate is thereby limited by the color filter layers adjacent to the recess portion.
5. The method as claimed in claim 3 , wherein the second spacer is inserted in the recess portion and movement of the array substrate is thereby limited by the color filter layers adjacent to the recess portion.
6. The method as claimed in claim 3 , wherein the recess portion extends along the first and second conductive lines and the first and second spacers are both inserted in the recess portion, thereby limiting movement of the array substrate.
7. The method as claimed in claim 1 , wherein the first spacer comprises resin, polymer or silicon compound.
8. The method as claimed in claim 3 , wherein the second spacer comprises resin, polymer or silicon compound.
