Board device and method for manufacturing display element
View Patent ↗A pillar-shaped spacer is disposed at the position between the boundary line of adjacent liquid crystal cells and an OLB terminal so as to face the end portion of the OLB terminal and so as to be interposed between a first large-size substrate and a second large-size substrate. Even when the respective liquid crystal cells are separated from one another along the boundary lines of the adjacent liquid crystal cells, exfoliation of the OLB terminals is prevented by the pillar-shaped spacers, so that extra cutting margins between the adjacent liquid crystal cells can be reduced and the manufacturing performance and the built-in number of the liquid crystal cells can be enhanced.
1. A board device having a first substrate and a second substrate disposed so as to face the first substrate, and a plurality of display elements adjacent to one another at least along a predetermined direction, and separable from one another, wherein
each of the display elements comprises:
a display area,
a non-display area provided along the predetermined direction and adjacent to the display area, and
a plurality of terminal pads in the non-display area on the first substrate and electrically connected to the display area; and
the board device includes pillar-shaped spacers disposed in the non-display area between a boundary line of the display elements and the terminal pads and disposed between the first substrate and the second substrate, so that a cutting margin of the first substrate is not required.
2. The board device according to claim 1 , wherein each pillar-shaped spacer is disposed to face one of the terminal pads.
3. The board device according to claim 1 , wherein each pillar-shaped spacer is disposed to face a location between two of the adjacent terminal pads.
4. The board device according to claim 1 , wherein each pillar-shaped spacer is disposed for every at least two of the plurality of terminal pads.
5. A display element manufacturing method of separating display elements from a board device having a first substrate, a second substrate disposed so as to face the first substrate, and a plurality of display elements adjacent to one another at least along a predetermined direction, each of the display elements comprising a display area, a non-display area provided along the predetermined direction and adjacent to the display area, and a plurality of terminal pads in the non-display area on the first substrate and electrically connected to the display area, the method comprising:
providing a pillar-shaped spacer disposed in the non-display area between a boundary line of the non-display area of one of the display elements and the display area of an adjacent one of the display elements, and the terminal pads, and between the first substrate and the second substrate, so that a cutting margin of the first substrate is not required, and
separating the display elements along the boundary line.
6. The display element manufacturing method according to claim 5 , wherein the pillar-shaped spacer is disposed to face one of the terminal pads.
7. The display element manufacturing method according to claim 5 , wherein the pillar-shaped spacer is disposed to face a location between two of the adjacent terminal pads.
8. The display element manufacturing method according to claim 5 , wherein the pillar-shaped spacer is disposed for at least two of plurality of terminal pads.
