PROBLEM TO BE SOLVED: To provide a reflection type display element which can perform display with high white reflectivity and a high contrast ratio, can be driven with a low voltage, and can respond fast. SOLUTION: Disclosed is the reflection type display element characterized in that a display electrode made of a substrate with a transparent conductive film and a counter electrode made of a substrate with a conductive film are arranged at an interval having conductive film sides opposed to each other and a display layer containing an EC composition carrying an organic EC compound in conductive or semiconductor particulates and white pigment particles having larger primary particle sizes than the conductive or semiconductor particulates is provided on the transparent conductive film of the display electrode.
