PLANAR PANEL DISPLAY SPACER PRODUCING METHOD AND PLANAR PANEL DISPLAY SPACER

摘要

The invention relates to a planar panel display spacer producing method, including a first cutting step for cutting a base plate (10) formed by a sintered body containing Al2O3 and TiC along a pair of first cutting planes (91) parallel to each other which cross the main surface (10A) of the base plate (10) to thereby form a first cut piece (30), and a second cutting step for cutting the first cut piece along a pair of second cutting planes parallel to a surface (30A) corresponding to the surface of the base plate in the first cut piece to thereby obtain a second cut piece. Thereby, the base plate containing AlTiC is divided into parts in the direction of the thickness, thus forming a second cut piece thinner than the base plate; therefore, using this second cut piece as a spacer for a planar panel display suppresses the deviation of electron beams in the planar panel display, thereby suppressing the blurring of images.
