    摘要： The present invention provides a liquid crystal display device including a pair of electrode substrates and a display medium sandwiched between the electrode substrates and including a polymeric wall and liquid crystal regions at least partly surrounded by the polymeric wall. In this liquid crystal display device, the polymeric wall is tightly attached to both the electrode substrates. Furthermore, the invention also provides a method for producing a liquid crystal display device including a pair of electrode substrates, at least one of which is transparent, and a display medium including a polymeric wall and liquid crystal regions at least partly surrounded by the polymeric wall and sandwiched between the electrode substrates. This method includes the steps of injecting a mixture including liquid crystal and a photopolymerizable material between the electrode substrates; and irradiating the mixture with light having light intensity distribution so as to cause phase-separation between the liquid crystal and the photopolymerizable material, thereby forming the liquid crystal regions in weakly irradiated areas.
