A display panel apparatus includes a substrate and an organic electro-luminescence unit that includes an array. The array is above the substrate and includes a red, a green, and a blue pixel. A glass layer is above the organic electro-luminescence unit. A resin layer is between the glass layer and the organic electro-luminescence unit. A surface of the resin layer that is on a side toward the organic electro-luminescence unit includes concaves. Each of the concaves is concaved toward the glass layer and corresponds to one of the pixels. Lens resins are each in one of the concaves and include a surface that is substantially coplanar with the surface of the resin layer. A refractive index of the lens resin in the concave that corresponds to the blue pixel is greater than a refractive index of the lens resin in the concave that corresponds to the red pixel.
