There is provided a display apparatus comprising: first display means including a first display section; and second display means including a second display section and a non-display section located at an outer periphery of the second display section; wherein partial area of a display surface of the first display section of the first display means faces the non-display section of the second display means; and wherein portion of the non-displaying section of the second display means, which is facing the display surface of the first display section is provided with a transmission section configured to transmit light from the first display section.

Display apparatus

A display unit includes a plurality of panels joined to each other into one display screen. Each of the panels is formed by using organic EL devices. In this display unit, a seal material is applied to a joint portion between adjacent two of the panels in such a manner as to cover the joint portion, to thereby suppress permeation of moisture, air, and the like in the organic EL devices.

Display unit

A bidirectional signal transmission circuit includes: a buffer element for reducing the impedance of a signal line; a signal line disposed between input terminals in both ends of the bidirectional signal transmission circuit; and a signal line disposed between output terminals in these ends. The signal lines are parallel to each other. A signal supplied from the exterior of the bidirectional signal transmission circuit is sequentially transmitted from one end to the other end of this circuit and is then output as an output signal from the other end in order to confirm the sequential transmission at the exterior. The transmitting direction is changeable between these ends in response to a switching signal supplied from the exterior. The buffer element for reducing the impedance of the signal line is disposed in at least one end of the signal line arranged between the output terminals.

Bidirectional signal transmission circuit

A magneto-optical recording medium, which is for recording and reproduction of information by focusing of light of a wavelength/numerical aperture of about 1000 nm or less, has a light transmitting first dielectric layer having a first surface to which light strikes. A magneto-optical recording layer is formed on a back surface of the first surface of the first dielectric layer. A light transmitting metal layer is formed on the magneto-optical recording layer to a predetermined thickness required for dispersion of heat (about 10 nm or more) from the magneto-optical recording layer and having a larger heat conductivity than the magneto-optical recording layer. A light transmitting second dielectric layer is formed on the light transmitting metal layer. A metal reflective layer is formed on the second dielectric layer and reflects the light.
