A method for forming a uniformly-spaced plastic substrate liquid crystal cell (100) includes the step of forming a cell with a liquid crystal-monomer mixture (150) disposed between upper and lower plastic substrates (111, 112). The cell (100) is then exposed to ultraviolet light (170) causing the monomer to be selectively polymerized to form support walls (108) between substrates (111, 112) of the cell in the light-intense areas. The monomer may be selectively polymerized by exposing the cell (100) through a mask (180, 188). The distance between the substrates (111, 112) is maintained before the walls (108) are formed by dispersing plastic ball spacers (114) between the substrates (111, 112). During exposure to the UV light, the substrates (111, 112) are sandwiched between substantially planar supports (182, 184) to maintain contact between the substrates (111, 112) and the spacers (114) and thus a uniform distance between the substrates (111, 112).
