发明名称 MANUFACTURE OF LIQUID CRYSTAL DISPLAY UNIT
摘要 PURPOSE:To simplify manufacturing processes by using a photosensitive polyimide resin and putting an electrode or an electrode and a filter in operation as an effective mask and thereby unifying sealing processed and scattering processes of spacers. CONSTITUTION:To make the space between two counter electrodes 21, 23 con stant, a polyimide film 3 is left selectively to make the height constant, and further, spacers and orientation films of polyimide group, the same material as a sealing material 6 are brought into close contact by press cure processes. Consequently, the space between two orientation films can be made constant within the range of specified thickness, for instance + or -0.5mu. Especially, in a large area liquid crystal panel as large as, for instance, 20cmX30cm having 400X1,920 dots, having active matrix structure, unnecessary swelling of central part and approximation between two electrodes can be prevented.
