Liquid crystal panel having low-resistance common electrode layer
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.
