The problem of the analysis of multilayer structure LCD screens internal re-reflection influence on the energetic reflection coefficient is being studied. The reason of the screen structure internal re-reflection existence is external sun rays incidence on the screen plane which is a significant problem for the avionics item designing domain knowledge. The effects of reflection, refraction and transparency which may appear in the LCD screen multilayer structure and also its influence on the diffuse and specular reflection coefficients are being studied. There is a reflection and refraction optical multifilm system. There are some mathematical expressions which enable to evaluate the layer structure LCD screen internal re-reflection influence on the reflection coefficient values using matrix calculation of the thinlayer system energetic characteristics. There are some optical systems and mathematical expressions which define the indirect measurement rules for the diffuse and specular reflection coefficients which depend on the external illumination incidence level.
