Abstract: In a method of forming a thin light guide plate which includes a compression step in an injection molding step, an optical pattern is liable to be adhered to a mold. Further, in removing the light guide plate from the mold using an ejector pin, a stress is concentrated on a local area of the light guide plate thus generating warping, deformation or irregularities in size of the light guide plate. To overcome such drawbacks, a liquid crystal display device is configured such that an optical pattern portion is compressed, and the light guide plate is removed by making use of a peripheral portion of a mold thus preventing the generation of stress in a local area of the light guide plate due to an ejector pin.

Abstract: In a display mode, a signal driving circuit (DAC) transmits image signals to the pixels selected by a scanning circuit for display and first switches of switch units. Then, a power supply circuit supplies a current corresponding to the transmitted signal to the pixels. Then, organic EL elements provided in the pixels are driven to emit light, thereby displaying an image. In order to correct the deterioration of the organic EL elements, first, a constant current flows from a current source to the organic EL elements of the pixels selected by a scanning circuit for detection and second switches and a voltage corresponding to the constant current applied to the organic EL element is detected. The detected voltage is input to an AD converter through a buffer amplifier, and the AD converter converts the voltage into a digital value, and transmits the digital value to a signal correction control unit. When the organic EL element deteriorates, the detected digital value varies.

Abstract: In a liquid crystal display device small in the size and having a narrow frame, an alignment film can be coated by ink jet printing, by coating a rapidly drying peripheral alignment film 109 in the shape of a frame to a TFT substrate 100 having a display region having pixel electrode 107 and a peripheral region thereof by ink jet printing, and then coating a display region alignment film 108 drying slower but excellent in the leveling effect by ink jet printing. While the display region alignment film 108 dries slowly, since the peripheral alignment film 109 formed to the periphery functions as a stopper, the shape of the alignment film can be defined accurately, thereby enabling to prevent lowering of the adhesion of the seal member 20 under the effect of the alignment film. This can be applied also on the side of the counter substrate 200.
