Abstract: In a display device including organic EL elements OLED, a p-channel switching transistor T8 is connected at a conductive terminal to a channel region of a p-channel drive transistor T4. When holes are trapped in trap levels within the channel region of the drive transistor T4 while the display device presents a white display image, this configuration enables the holes to be extracted through the switching transistor T8 to an initialization line Vini. Consequently, a drive current flows through the drive transistor T4 in accordance with a data voltage, resulting in no perceptible afterimage even when a gray display image is presented during an immediately subsequent frame.

Abstract: In the present embodiment, a sealing agent (50) sealing two substates contains a low melting-point glass material and is adhered to each of a first substrate (10) and a second substrate (20), a barrier rib (60), which is formed in such a manner as to surround the outer periphery of an electronic element (30), is disposed between the sealing agent (50) and the electronic element (30), and between the first substrate (10) and the second substrate (20), and the sealing agent (50) is spaced apart from the barrier rib (60). As a result, a deterioration of the electronic element, caused by the heat produced when sealing, may be prevented while the electronic element formed between the two substrates is protected from moisture and oxygen.

Abstract: A liquid crystal display panel (100A, 100B) includes a transverse electric field mode liquid crystal cell (10), a first polarizing plate (22A, 22B) disposed on a back surface side of the liquid crystal cell (10), and a second polarizing plate (24A, 24B) disposed on a viewer's side of the liquid crystal cell (10). A liquid crystal layer (18) contains a nematic liquid crystal whose dielectric anisotropy is negative. The liquid crystal layer (18) has And of less than 550 nm, where Δn is the birefringent index of the nematic liquid crystal and d is the thickness of the liquid crystal layer. The liquid crystal layer (18) is in a twist alignment state when no voltage is applied. When polarized light whose Stokes parameter S3 takes on an absolute value |S3| of 1.00 enters the liquid crystal layer (18), |S3| of polarized light having perpendicularly passed through the liquid crystal layer (18) is 0.85 or greater. The first polarizing plate (22A, 22B) and the second polarizing plate (24A, 24B) are circularly polarizing plates or elliptically polarizing plates whose ellipticity is 0.422 or greater.
