Abstract

An exemplary liquid crystal panel ( 20 ) includes a first substrate ( 22 ), a second substrate ( 24 ) facing toward the first substrate ( 22 ), a liquid crystal layer ( 23 ) sandwiched between the two substrates, and a plurality of the conductive adhesive blocks ( 225 ) in the non-displaying region. The first substrate includes a non-displaying region ( 222 ). A transparent conductive layer ( 226 ) is disposed at a surface of the first substrate and capable of transmitting a common voltage signal to the liquid crystal layer. The first substrate at the non-displaying region includes protrusions ( 253 ) defining a plurality of gaps ( 254 ) therebetween. The transparent conductive layer covers the protrusions including parts of the protrusions defining the gaps. The conductive adhesive blocks contact the transparent conductive layer at the non-displaying region.

Claims (14)

1. A liquid crystal panel, comprising:

a first substrate defining a non-displaying region;

a second substrate facing toward the first substrate;

a liquid crystal layer sandwiched between the first substrate and the second substrate;

a plurality of conductive adhesive blocks in the non-displaying region; and

a transparent conductive layer provided at a surface of the first substrate and capable of transmitting a common voltage signal to the liquid crystal layer;

wherein the first substrate at the non-displaying region comprises a plurality of protrusions defining a plurality of gaps therebetween, the transparent conductive layer covers the protrusions including parts of the protrusions defining the gaps, the conductive adhesive blocks contact the transparent conductive layer, and a thickness of the transparent conductive layer in the gaps is greater than a thickness of the transparent conductive layer on other portions of the protrusions.

2. The liquid crystal panel of claim 1 , wherein the transparent conductive layer in the gaps does not protrude below a bottom extremity of the transparent conductive layer on the other portions of the protrusions.

3. The liquid crystal panel of claim 1 , wherein the protrusions are formed at a same layer.

4. The liquid crystal panel of claim 1 , wherein the first substrate further defines a displaying region within the non-displaying region, and in the display region, a color filter layer is provided on the first substrate, the color filter layer comprising a plurality of color filter units and a plurality of black matrix units that fill gaps between the color filter units.

5. The liquid crystal panel of claim 4 , wherein the protrusions and the color filter units are made of substantially the same material.

6. The liquid crystal panel of claim 5 , wherein the color filter units are provided at a same layer in the non-displaying region to form the protrusions.

7. The liquid crystal panel of claim 4 , wherein the protrusions and the black matrix units are made of substantially the same material.

8. The liquid crystal panel of claim 1 , wherein each of the conductive adhesive blocks corresponds to the plurality of protrusions.
