ORIENTED FILM LIGHT ORIENTING POLARIZATION LIGHT IRRADIATING DEVICE FOR LIQUID CRYSTAL DISPLAY ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a polarization light irradiating device capable of forming an oriented film for a liquid crystal display element by light orientation. ;SOLUTION: The light containing ultraviolet light radiated from a discharge lamp 1 is converged by an ellipse convergent mirror 2, and is reflected by a first plane mirror 3 to be made incident on an integrator lens 5 through a shutter 4. The light outgoing from the integrator lens 5 is reflected further by a second plane mirror 6, and is made parallel rays of light by a collimate lens 7 to be made incident on a polarizing element 8. The polarizing element 8 is one that plural pieces of glass plates are parallel arranged at an interval, and these glass plates are,arranged tilting by a Brewstar angle for incident light, and the element 8 passes P polarization through, and reflects the majority of S polarization. The P polarization outgoing from the polarizing element 8 irradiates a work W through a mask M.;COPYRIGHT: (C)1998,JPO
