Title:
MANUFACTURE OF BLACK MATRIX
Document Type and Number:
Japanese Patent JPH05297216
Kind Code:
A
Abstract:
PURPOSE:To enhance the reliability of the seal strength of a black matrix, wherein the active layer needs not transparency and tight attachment thereto be obtained while the permeability inherent in the pixel is maintained, by using as a coating a sol acquired through hydrolysis of a specific organic compound, and subjecting the applied sol to the baking process. CONSTITUTION:Alkoxy organic compound on the like given by a formula: M(OR1)m(OR2)nXpYq is hydrolyzed to form a sol, which is either solely or in combination applied to a transparent base board 1 and baked to provided thereover an active layer 2 which has fine pores. The whole surface of this active layer 2 is subjected to non-electrolytic plating, and thereover a resist layer 5 is furnished in the form of lattice or netting, and that portion of active layer not covered with the resist layer is removed by etching to produce the resultant active layer which has black matrix 6 over the whole surface, formed in lattice or netting, and presents light shutting effect. The resist layer 5 is exfoliated. In the formula, M is one element of magnesium, calcium, etc., R1 and R2 are alkyl radical or acyl radical, and X and Y are hydrogen atom, chlorine atom, or hydroxyl radical.
