Reflective plate for reflective liquid crystal display and method for making the same

A method for making a reflective plate used in an LCD, comprising the steps of:

• preparing a base substrate;
• dispersing a plurality of spacers on the base substrate to form an unevenly non-uniformly surfaced layer on the substrate;
• and
• depositing a reflective layer on the base substrate to cover the spacers;
• wherein a surface roughness (k) of the reflective layer is 6-10 degree when the surface roughness (k) is defined by a following formula;
• k = 1 L ⁢ ∫ 0 L ⁢ α 2 ⁢ ⅆ x
• where the L is a surface length of the substrate and α is a mean angle of surface inclination.

A method for making a reflective plate used in an LCD, comprising the steps of:

• preparing a base substrate;
• dispersing a plurality of spacers on the base substrate to form an uneven layer on the substrate;
• depositing a reflective layer on the base substrate to cover the spacers, wherein the dispersing step further includes:
• pre-heating a lump of thermosetting resin;
• grinding the thermosetting resin into a powder;
• mixing the powder with isopropyl alcohol;
• spraying the mixture on the base substrate in a randomly scattered pattern;
• heating the sprayed mixture at a temperature higher than that for the pre-heating;
• melting the mixture;
• and
• hardening the mixture so that an uneven non-uniform surface layer is formed on the base substrate.
