Liquid crystal display panel and manufacturing method for the same
View Patent ↗A liquid crystal display panel is provided and includes a first substrate and a second substrate disposed to face each other with a liquid crystal layer held therebetween. The first substrate has peripheral circuit wires formed in a peripheral area surrounding a display area, and the second substrate is disposed to face the first substrate so that the peripheral circuit wires of the first substrate are exposed. A resin layer having a predetermined width is formed on that end part of the second substrate on the side of facing the first substrate which is located on the side of the peripheral circuit wires of the first substrate.
1. A liquid crystal display panel comprising:
a first substrate and a second substrate disposed to face each other with a liquid crystal layer held therebetween,
the first substrate having peripheral circuit wires formed in a peripheral area surrounding a display area, and
the second substrate being disposed to face the first substrate so that the peripheral circuit wires of the first substrate are exposed,
wherein a resin layer having a predetermined width is formed on an end part of the second substrate on the side thereof facing the first substrate, the end part overlapping the peripheral circuit wires of the first substrate in plan view, and
wherein a scribe mark serving as a reference for drawing a scribe line is formed on the second substrate, and the resin layer is formed on a portion of the second substrate that overlaps the scribe line and does not overlap the scribe mark in plan view.
2. The liquid crystal display panel according to claim 1 , wherein the resin layer comprises at least one layer including a material selected from the group consisting of a material used to form a light-shielding layer, a material used to form an overcoat layer, a material used to form a color filter layer, and a material used to form a photo-spacer.
3. The liquid crystal display panel according to claim 1 , wherein the resin layer is formed in a plurality of separate resin layer areas to correspond to areas that include the peripheral circuit wires of the first substrate in plan view.
4. A method of manufacturing a liquid crystal display panel comprising:
preparing a precursor of the liquid crystal display panel which includes a first substrate having peripheral circuit wires formed in a peripheral area surrounding a display area, and a second substrate being disposed to face the first substrate, with a liquid crystal layer held between the first substrate and the second substrate;
forming a scribe mark serving as a reference for drawing a scribe line on the second substrate;
forming a resin layer on the second substrate on a side thereof facing the first substrate and to overlap the peripheral circuit wires in plan view, the resin layer being formed on a portion of the second substrate that overlaps the scribe line and does not overlap the scribe mark in plan view; and
scribing the second substrate along the scribe line so as to expose the peripheral circuit wires of the first substrate.
5. The method of manufacturing a liquid crystal display panel according to claim 4 , further comprising:
adhering the first and second substrates to each other with a seal material so that at least a part of the seal material adheres the first and second substrates to each other without the resin layer in between the seal material and the second substrate.
