ABSTRACT:
A glass substrate for a reflective mirror of a rear projection television (RPTV) which ensures display quality by quantitative control, and can reduce control cost and manufacture cost is provided. A reflective mirror3of the rear projection television (RPTV) includes a float glass plate (glass substrate)1formed to have a plate thickness of 3 mm by a float process, and a reflection enhancing film2constituted of aluminum (Al) formed on one surface1aof the glass substrate1by a sputtering method. In the measurement condition of a cut-off value of 0.8 to 8 mm, the maximum amplitude of a filtered waviness curve is 0.1 μm or less, the maximum value of a viewability index value γ (=A/D3) in a range of spatial frequencies 2 to 500/mm by spectral analysis of the filtered waviness curve is 0.02 (/m2) or less, and an integral value of the viewability index value γ is 2.0 (/m3) or less.
