In recent years, e‐readers have spread to many countries. Most of e‐readers have a reflective type of display called e‐paper. The general view is that under conditions of low illuminance, readability of the e‐paper display is poor. However, most recent e‐readers have a built‐in light system. This system would improve the readability of the e‐paper display under low illuminance conditions. We carried out experiments to evaluate the readability e‐paper devices using different systems. In the experiments, we conducted subjective evaluations under staged illuminance conditions by using English words. This study found that e‐paper devices with built‐in light under low illuminance condition were superior in terms of readability.
