Abstract

PURPOSE:To improve a display effect, by forming the surface of an electrode formed on an opaque lowr substrate, in the uneven shape, and constituting so that an area of the part whose surface tilt angle is <=30 deg. against the horizontal surface occupies <=70% of the whole electrode area. CONSTITUTION:The surface of an aluminum electrode is fomed in an uneven shape having amplitude 41, and it is constituted so that on its surface, an area of the part whose tilt ange theta is <=30 deg. against the horizontal surface occupies >=70% of the whole electrode area, an area whose tilt angle theta is >=2 deg. in the part which is <=30 deg. against the horizontal surface occupies >=20% of the whole area, and diffusion of an area of the part corresponding to each angle when the tilt angle theta extending from 5 deg. to 25 deg. has been partitioned by 1 deg. each is >=2 deg.. According to such constitution, an incident light beam is scarcely brought to multipath reflection, intensity of reflected rays is large, and a display effect is improved.
