Liquid crystal display device comprising an electrode having a connection portion with a dielectric member thereon as to contact a pixel electrode of the second substrate, and manufacturing method for the same
View Patent ↗A liquid crystal display device is disclosed. The liquid crystal display includes a liquid crystal layer disposed between substrates opposing each other. A pixel of the liquid crystal display is alignment-divided into a plurality of sub-pixels. A dielectric member is provided on a connection portion where the sub-pixels are electrically connected.
1. A liquid crystal display device comprising a liquid crystal layer disposed between first and second substrates,
wherein,
said display device comprises at least one pixel which is alignment-divided into a plurality of sub-pixels,
said sub-pixels are connected together by an electrode on said first substrate,
a connection portion is a portion of said electrode exposed by notches or slit between said sub-pixels,
said connection portion has a width less than a width of said sub-pixels, and
said connection portion has a dielectric member thereon, the dielectric member on the electrode of the first substrate being disposed so as to contact a pixel electrode of the second substrate.
2. The liquid crystal display device according to claim 1 , wherein:
a center of each of the sub-pixels includes an alignment control member on the pixel electrode of the second substrate.
3. The liquid crystal display device according to claim 1 , further comprising a light shielding element on said first substrate on a side facing away from said second substrate.
4. The liquid crystal display device according to claim 1 , further comprising a light shielding element on said second substrate on a side facing away from said first substrate.
5. The liquid crystal display device according to claim 1 , wherein the dielectric member is disposed around the electrode on the first substrate.
6. The liquid crystal display device according to claim 1 , wherein the dielectric member serves also as a spacer that maintains a space between the first and second substrates.
7. The liquid crystal display device according to claim 1 , wherein the liquid crystal layer is of a vertical alignment type.
8. A method of manufacturing a liquid crystal display device which includes a liquid crystal layer disposed between first and second substrates, and in which a pixel is alignment-divided into a plurality of sub-pixels, the method including the steps of:
forming an electrode on the first substrate on a side which will face said second substrate;
forming notches or a slit between said sub-pixels electrically connected by a connection portion so that said connection portion has a width less than that of said sub-pixels; and
forming a dielectric member on said connection portion, the dielectric member on the electrode of the first substrate being disposed so as to contact a pixel electrode of the second substrate.
9. The manufacturing method of the liquid crystal display device according to claim 8 , wherein
the dielectric member is formed to connect to the first and second substrates, and the dielectric member is made to serve also as a spacer to keep a space between the substrates.
10. The manufacturing method of the liquid crystal display device according to claim 8 , wherein
the dielectric member is formed around the electrode or on a part thereof.
