Patent number: 8704980Abstract: A display panel comprises a first and a second substrates and a BP liquid crystal layer. A first electrode is provided on the first substrate, a second electrode is provided on the second substrate, and reflection portions each having a first and a second reflection surfaces are provided between the first and second substrates. When light is transmitted to the panel, the light is reflected on the first reflection surface of the reflection portion and the light after the first reflection is transmitted to an adjacent reflection portion through the liquid crystal layer and is reflected on the second reflection surface of the adjacent reflection portion. When different voltages are applied, the liquid crystal layer will shift the phase position of the light passing therethrough, while when there is no voltage, the liquid crystal layer will not shift the phase position of the light passing therethrough.Type: GrantFiled: March 3, 2011Date of Patent: April 22, 2014Assignee: Infovision Optoelectronics (Kunshan) Co.
