Method for curing sealant used when sealing an LCD panel

1. A method for curing a sealant when sealing a liquid crystal display panel, the method comprising:

providing the liquid crystal display panel with a sealant for sealing the liquid crystal display panel; and

curing the sealant by applying light having a double-slit diffraction pattern obtained by using a mask having two slits.

2. The method as claimed in claim 1 , wherein the light is ultraviolet light.

3. A method for manufacturing a liquid crystal display panel, comprising:

providing a first substrate, and forming a color filter film and a black matrix on the first substrate;

providing a second substrate, and applying a sealant on the second substrate;

applying liquid crystal onto the second substrate;

attaching the first substrate to the second substrate; and

curing the sealant by applying light having a double-slit diffraction pattern obtained by using a mask having two slits.

4. The method as claimed in claim 3 , wherein the light is ultraviolet light.

5. A method for manufacturing a liquid crystal display panel, comprising:

providing a first substrate and forming a color filter film and a black matrix on the first substrate;

providing a second substrate with a sealant applied thereon;

applying liquid crystal on the second substrate;

attaching the first substrate to the second substrate; and

curing the sealant by applying light having a double-slit diffraction pattern obtained by using a mask having two slits.

6. The method as claimed in claim 5 , wherein the light is ultraviolet light.
