    Abstract: The master device includes a first pad connected to a slave device through a first wire; a second pad connected to the slave device through a second wire; and a communication interface to transmit a communication control signal to the slave device through the first pad, and, through the second pad, to transmit a first data signal synchronized with the communication control signal to the slave device and to receive a second data signal synchronized with the communication control signal from the slave device. The first data signal is transmitted to the slave device by the master device in a write mode and the second data signal is transmitted to the master device by the slave device in a read mode. The communication interface is configured to start the read mode by transiting the communication control signal from a first voltage level to a second voltage level while the second pad has a predetermined voltage level.

    Abstract: A display device includes: a base layer including a display area including an emission area and a non-emission area adjacent to the emission area, and a non-display area around the display area; a light emitting element in the emission area on the base layer; a color filter layer located above the light emitting element; and a light blocking pattern on the light emitting element and including a first light blocking pattern in the non-emission area and a second light blocking pattern in the non-display area. The first light blocking pattern and the second light blocking pattern are different in thickness from each other.
