Abstract
The invention relates to a reflective display panel (), comprising a plurality of pixels (), each having a modulative portion (-) which is controllable between light-modulation states, and a non-modulative portion (). The reflective display panel () comprises a redirection sheet () having a plurality of redirecting structures () each being configured to redirect ambient light incident thereon towards an adjacent modulative portion (-). Through the invention, the portion of the light which would otherwise have hit the non-modulative portion of the pixel and would not have contributed constructively to the image forming of the display panel is instead directed towards the modulative portion of the pixel and can thereby contribute to the brightness as well as to the contrast of the reflective display panel.
