Abstract

On an application stage of resin are provided two (2) sets of dispensers 20 and 40 . The one dispenser 20 supplies the resin directing to an upper side corner on a liquid crystal cell 1 , while the other dispenser 40 directing to a lower side corner thereon. The dispenser 40 has a syringe 41 and a needle-like nozzle 42 , and the needle-like nozzle 42 emits the resin, directing upward obliquely, onto the lower side corner. Thereby, the resin can be supplied between an edge portion of a lower substrate and a lower surface of a connecting board, but without turning over the panel for display, such as, a liquid crystal cell, etc.

Claims (22)

1. A method for applying resin onto an upper side corner defined between a projection portion of a lower substrate and an upper substrate, and a lower side corner of a draw-out portion of the lower substrate from a flexible board, on a panel being made up with two pieces of substrates, in which at least two sides of the lower substrate are projected from the upper substrate and are attached with a plural number of flexible boards at the projection portions of the lower substrate, at a predetermined pitch distance therebwtween, comprising the following steps:

disposing dispensers for applying the resin, at said upper side corner and said lower side corner, under non-contacting condition therewith;

applying the resin directing from each of said dispensers to said upper side corner and said lower side corner, respectively, during when either one of said panel or said dispenser is moved with respect to the other;

applying the resin almost uniformly over a total length of said panel, on the upper side corner; and

applying the resin onto each attaching portion of each of said flexible boards, on the lower side corner.

2. A manufacturing method of a panel for display, comprising manufacturing a panel for display by using the panel, on which the resin is applied by means of the resin applying method on a panel described in the above claim 1 .

3. A method for applying resin onto an upper side corner defined between a projection portion of a lower substrate and an upper substrate, and a lower side corner of a draw-out portion of the lower substrate from a flexible board, on a panel being made up with two pieces of substrates, in which at least two sides of the lower substrate are projected from the upper substrate and are attached with a plural number of flexible boards at the projection portions of the lower substrate, at a predetermined pitch distance therebetween, comprising the following steps:

disposing dispensers for applying the resin, at said upper side corner and said lower side corner, under non-contacting condition therewith;

applying the resin directing from each of said dispensers to said upper side corner and said lower side corner, respectively, during when either one of said panel or said dispenser is moved with respect to the other, wherein the resin is applied almost uniformly over a total length of the panel on the upper side corner and is applied to each attaching portion of each of the flexible boards on the lower side corner; and

drying the resin applied thereon.

4. A manufacturing method of a panel for display, comprising manufacturing a panel for display by using the panel on which the resin is applied by means of the resin applying method on a panel described in the above claim 3 .

5. A method for applying resin onto an upper side corner defined between a projection portion of a lower substrate and an upper substrate, and a lower side corner of a draw-out portion of the lower substrate from a flexible board, on a panel for a display being made up with two pieces of substrates, in which at least two sides of the lower substrate are projected from the upper substrate and are attached with a plural number of flexible boards at the projection portion of the lower substrate, at a predetermined pitch distance therebetween, comprising the following steps:

disposing dispensers for applying the resin, at said upper side corner and said lower side corner, under non-contacting condition therewith;

applying the resin directing from each of said upper side corner and said lower side corner, respectively, during when either one of said panel or said dispenser is moved with respect to the other, wherein the resin is applied almost uniformly over a total length of the panel on the upper side corner and is applied to each attaching portion of each of the flexible boards on the lower side corner; and

drying the resin applied thereon.

6. The method for applying resin according to claim 5 , wherein said panel for a display is made up with said two pieces of substrates encapsulating a liquid crystal material therebetween.

7. A method for applying resin onto an upper side corner defined between a projection portion of a lower substrate and an upper substrate, and a lower side corner of a draw-out portion of the lower substrate from a flexible board, on a panel for a display being made up with two pieces of substrates, in which at least two sides of the lower substrate are projected from the upper substrate and are attached with a plural number of flexible boards at the projection portions of the lower substrate, at a predetermined pitch distance therebetween, comprising the following steps:

disposing dispensers for applying the resin, at said upper side corner and said lower side corner, under non-contacting condition therewith;

applying the resin directing from each of said dispensers to said upper side corner and said lower side corner, respectively, during when either one of said panel or said dispenser is moved with respect to the other;

applying the resin almost uniformly over a total length of said panel, on the upper side corner; and

applying the resin onto each attaching portion of each of said flexible boards, on the lower side corner.

8. The method for applying resin according to claim 7 , wherein said panel for a display is made up with said two pieces of substrates encapsulating a liquid material therebetween.
