Display panel, laminated substrate, liquid crystal cell and method of manufacturing laminated substrate
A display panel, laminated substrate, and liquid crystal cell which includes a pair of facing substrates bonded together with a sealing material. One or both of the substrates includes at least one corner portion on which a plurality of protruding pads are formed, the pads assisting in dispersion of the sealing material during bonding of the substrates to prevent sealing material from moving inwardly and possibly adversely affecting the display region of the resulting structure. A method of making such a laminated substrate is also provided.
1. A liquid crystal cell comprising:
a substantially rectangular first substrate having a color filter layer and four corner portions;
a substantially rectangular second substrate being disposed opposite to said first substrate and having driver elements for liquid crystal materials;
a sealing material of a frame shape for joining said first substrate and said second substrate; and
a plurality of pads having a tapered shape positioned on each of said corner portions of said first substrate or forming a part of said first substrate, said pads oriented in a substantially radial pattern in said corner portions.
2. The liquid crystal cell according to claim 1 , wherein said pads are each comprised of the same material as said color filter layer.
3. The liquid crystal cell according to claim 1 further including another plurality of pads, each of said another plurality of pads being oriented along a side portion of said first substrate.
4. The liquid crystal cell according to claim 1 wherein the number of pads positioned on each of said corner portions or forming part of said first substrate is four.
5. The liquid crystal cell according to claim 1 wherein each of said pads positioned on said corner portion is of substantially rectangular configuration.
6. The liquid crystal cell according to claim 1 wherein said pads positioned on said corner portion include a common outside edge.
