Title: Method for forming reflection layer of refective lcd
Inventor: CHOI SANG EON
IPC: G02F1/1335
Filed: 2000-06-26
Abstract: PURPOSE: A forming method of a reflecting plate for a reflective LCD(Liquid Crystal Display) is provided to improve transmissivity and viewing angle characteristics of a reflective LCD by forming an irregular reflecting plate having partial uniformity through a photosensitive film pattern having different thickness, width and density of each area. CONSTITUTION: A photoresist is coated on a glass substrate(11) and exposed by using at least one and more half tone masks. The photoresist is exposed with different exposure rates for each RGB(Red,Green,Blue) sub-pixel. The half tone mask is an exposing mask for making the thickness of a photosensitive film pattern partially different by making the transmissivity of UV(Ultra Violet) rays in a micro-pattern part relatively smaller than the transmissivity of UV of an aperture. The exposed photosensitive film is developed to form photosensitive film patterns(12a,12b,12c) having different thickness, width and density according to each sub-pixel. A metal film having a high reflectivity is deposited on the front surface of the glass substrate having the photosensitive film patterns to form an irregular reflecting plate(13). The reflecting plate has surface irregularities having different height, width and density of each sub-pixel area according to the thickness, width and density of the photosensitive film patterns. After that, PA(Polyamide,14) is coated on the reflecting plate to make the surface flat.
