Abstract
A liquid crystal display device includes first and second substrates facing each other and spaced apart by a uniform cell gap, an array element having a switching element on the first substrate and a first transparent electrode connected to the switching element, a first patterned spacer disposed on the array element having a first height less than the uniform cell gap, a second transparent electrode under the second substrate, a second patterned spacer disposed beneath the second transparent electrode, the second patterned spacer having a second height less than the uniform cell gap and connected to the first patterned spacer, a first alignment layer covering the first patterned spacer, a second alignment layer covering the second patterned spacer, and a liquid crystal material layer interposed between the first and second alignment layers, wherein the first and second spacers are connected to each other and a summation of the first and second heights of the first and second patterned spacers is equivalent to the uniform cell gap.
