Spacers for liquid crystal displays

A method of forming spacers, comprising the steps of:

• providing a first substrate having a first surface and a second surface wherein said first substrate is transparent and said first surface of said first substrate and said second surface of said first substrate are parallel to each other;
• providing a second substrate having a first surface and a second surface wherein said first surface of said second substrate and said second surface of said second substrate are parallel to each other;
• forming a number of opaque pads on said first surface of said first substrate;
• forming a first layer of positive photoresist on said first surface of said first substrate after said opaque pads have been formed;
• exposing said first layer of positive photoresist by means of a light beam illuminating said second surface of said first substrate thereby using said opaque pads as a mask;
• developing said first layer of positive photoresist thereby forming a first spacer pad on each said opaque pad;
• forming a second layer of positive photoresist on said first surface of said first substrate after said first spacer pads have been formed;
• exposing said second layer of positive photoresist by means of a light beam illuminating said second surface of said first substrate thereby using said opaque pads as a mask;
• developing said second layer of positive photoresist so that only that part of said second layer of photoresist directly over said opaque pads and said first spacer pads remains, thereby forming a second spacer pad on each of said first spacer pads;
• bringing together said first substrate and said second substrate so that said first surface of said second substrate contacts said second spacer pads;
• and
• placing liquid crystal material between said first surface of said first substrate and said first surface of said second substrate.
