摘要： An active-matrix substrate includes: two kinds of lines arranged in a matrix on an insulating plate; switching elements each provided in the vicinity of an intersection of the two kinds of lines; an insulating film for flattening, covering an entire surface of the insulating plate so as to flatten the uneven surface of the insulating plate due to the presence of the lines and the switching elements; and pixel electrodes provided in a matrix on the insulating film for flattening. A concave portion for preventing a short-circuit from occurring between the pixel electrodes during a production process is formed in a region of the insulating film for flattening which corresponds to a gap between pixel electrodes which are adjacent to each other. Also, a method for fabricating the active-matrix substrate includes the step of forming a concave portion for preventing a short-circuit from occurring between the pixel electrodes in an exposed portion of the insulating film for flattening at a gap between the pixel electrodes adjacent to each other, forming the concave portion by an ashing treatment after forming the pixel electrodes in a matrix.

摘要： It is an object to provide a display that can reliably shield visible light in the entire wavelength regions when viewed from an oblique direction and a viewing angle control element used for the display. A viewing angle control liquid crystal panel (2) is comprised of a liquid crystal cell (21) and an emission-side polarizing plate (22). When light having a part of wavelength components (R,G) in the visible wavelength regions enters at least at a predetermined angle, the liquid crystal cell (21) provides the incident light with a phase difference so as to function as a first light-shielding layer that shields the light of the R and G components not to pass through the emission-side polarizing plate (22). A retardation plate (4) and a polarizing plate (5) function as auxiliary light-shielding layers, more specifically, when the light that has passed through the first light-shielding layer enters at least at the predetermined angle, the retardation plate (4) provides the light with a phase difference so that at least light having a wavelength component (B) is shielded and thus not transmitted by the polarizing plate (5).
