ABSTRACT:
The present invention realizes an image display of high quality by eliminating a defective display which is attributed to a stepped portion of a light shielding film which is generated in a boundary region by exposure of two or more times using an exposure mask having a size smaller than a size of a display region. Assuming a width of a scanning line GL as WG, a width of a common line CL as WC, an interval between the scanning line GL and the common line CL as WP, and a width of a light shielding film BM1as WBM, the relationship WBM<WG+WC+WPis established. Further, both end peripheries of the light shielding film BM1are positioned between an end periphery of the scanning line GL at a side opposite to the common line CL and an end periphery of the common line CL at a side opposite to the scanning line GL.
