Title: Surface plate for display
Inventor: NONOGAKI SABURO
IPC: H01J29/32
Filed: 1986-08-29
Abstract: PURPOSE:To remarkably reduce mirror reflection, by forming a light transmitting layer having a refractive index larger than that of glass between a light absorptive layer and a glass surface plate. CONSTITUTION:A light transmitting titanium oxide layer 3 having a refractive index larger than that of glass is formed between a light absorptive layer 1 comprising a colloidal carbon layer in a black matrix and a transparent substrate 2 comprising a glass plate. Moreover, a light transmitting layer 4 made of silicon oxide, whose refractive index is smaller than that of the light transmitting layer 3, is piled on the light absorptive layer 1 and the light transmitting layer 3. Such layer composition allows incident light 10 to become reflected rays R1 and R2 on an interface between the glass surface plate 2 and the high refractive index layer 3, and on another interface between the layer 3 and the light absorptive layer 1, respectively. If thickness of the layer 3 is equal to a quarter of wavelength of the light in this layer, the reflected rays R1 and P2 have opposite phases and weaken each other. If both rays are equal in intensity, the total intensity becomes zero. Therefore, a refractive index of the light transmitting part in a black matrix can be remarkably decreased over the wide range of wavelength.
