Japan Display Inc. (株式会社ジャパンディスプレイ, Kabushiki-gaisha Japan Disupurei) (JDI) is an LCD technology joint venture by Sony, Toshiba, and Hitachi.


The Innovation Network Corporation of Japan (INCJ) financed the merger of Sony, Toshiba, and Hitachi's LCD divisions into one entity by investing two hundred billion yen.

The agreement was finalized November 15, 2011 and operations began April 1, 2012.[3]

The Innovation Network Corporation of Japan (INCJ) was split. The new entity INCJ, Ltd. is the major shareholder of Japan Display with 25,29 % of total shareholdings as of September 21, 2018.[4]

  • June 12 - JDC discloses that major changes are to be implemented due to sluggish sales in the Mobile Business Division (smartphones and tablets). One plant will be closed and another suspends operation. A major reduction of the workforce is also planned.[8]


JDI has developed several technologies to differentiate its LCD panels from those of its competitors.

  • Active-matrix displays driven by TFTs based on a low-temperature polycrystalline-silicon ("LTPS") process instead of amorphous silicon. These higher performance transistors allow a higher resolution (more ppi = pixels per inch).[9]
  • Most LCDs manufactured by JDI use the In-Plane-Switching concept, as do many of its competitors. JDI has developed an improvement for darker black pixels (true-black appearance), called "IPS-NEO", which reduces the light shining through from the backlighting.[10]
  • The conventional combination of a transparent touch-screen device in front of an LCD panel has been replaced by integrating the touch-screen function into the LCD panel itself, called "Pixel Eyes".[11]
  • For reflective LCDs without backlighting, JDI has developed an addressing technique using a thin-film memory device SRAM in addition to the conventional TFT for each pixel, so that a still image can be stored utilizing a small amount of energy.[12]


As JDI conducted an IPO during March 2014, some business information became available.[13]

It was reported that JDI was the major supplier of displays for Apple's iPhone.[14] $100 million investment was reported by Apple in June 2019, which raised market shares of Japan Display by 32%.[15]

In the 3 years after the IPO, JDI accumulated losses each year. A restructuring plan was announced in 2017, including closing down a production line in Japan and the layoff of approx. a third of the workforce.[16]
