Abstract
A method of forming a LCD device having spacers is described. A mixed material is then formed on a first substrate facing a second substrate by mixing a pre-spacer material and a protrusion material with a predetermined ratio. An exposure step and a development step are performed on the mixed material to pattern the mixed material to form protrusion-spacer structures. The protrusion-spacer structures having the same height. Each protrusion-spacer structure has both a protrusion and a spacer, wherein the protrusion is formed on the first substrate, and the spacer is formed only on the protrusion, one-to-one. The first substrate and the second substrate are sealed together, wherein the gap thickness between the first substrate and the second substrate is the same as the height of the protrusion-spacer structures.
