A liquid crystal layer is sealed between the couple of substrates with the pixel electrodes formed and the gaps are alternately disposed to form a staggered arrangement between the pair of pixel electrodes. The liquid crystal layer has pre-tilt regions where liquid crystal molecules are tilted. In these regions, the spacing between adjacent pre-tilt regions is smaller than spacing in the substrate surface direction between the gap of a pixel electrode on one substrate and the gap of a pixel electrode on the other substrate.

Abstract: An electron gun includes a grid electrode having a thin plate portion in which an electron beam aperture is formed, wherein the thin plate portion is formed by using a die and punch die to bulge a portion of a metal plate in the plate thickness direction to such an extent as to correspond to the desired dimension of the thin plate portion to form a bulged portion and cutting the bulged portion.
