Problems solved by technology

[0003] In order to improve the display effect of the OLED display device, the OLED display panel in the existing OLED display device includes an OLED display substrate, and a refraction layer formed on the surface of the OLED display substrate, so as to reflect the light emitted by the OLED display substrate through the refraction layer, so that the OLED The optical microcavity of the display panel is adjusted to increase the chromaticity of the light emitted by the OLED display panel; however, due to the relatively high selectivity of the optical microcavity of the OLED display panel to the wavelength of light, the OLED display panel The color coordinates of the displayed image shift greatly at different viewing angles, which seriously affects the display effect of the OLED display panel
