FINE CHEMICALS DIVISION, Products for LCD.

The recent innonovation and new product development in the area of high color clarity, adaptation for animated graphics, etc., for large screen LCDs is remarkable. Micropearl is a fine plastic sphere, the result of fine particle technology developed by Sekisui, and is essential to the large and clear color LCD displays. These particles are sprayed between the glass substrates to maintain the cell gap precisely and evenly.Sekisui provides a wide variety of Micropearl types and sizes that are universally used by LCD manufactures.

[Available Products]

	Spacer: for the liquid crystal cell or the peripheral sealing edges.
	Photosensitive Resin: for closing of the liquid crystal inlet.
