Abstract: In a liquid crystal display device having a display region defined by an area where a TFT substrate and an opposing substrate are superposed on each other, the present invention realizes a structure for avoiding breakage of a mechanically weak terminal section where the TFT substrate only extends. The terminal section where the TFT substrate only extends is mounted on a resin mold. Inside the resin mold, partition walls are formed to accommodate LEDs. By providing two partition walls in a pair at least in a center portion, an external pressure exerted on the center portion of the resin mold is distributed between the two partition walls and a maximum stress exerted on the terminal section of the TFT substrate is reduced.

Abstract: In a shadow mask color cathode ray tube, its shadow mask is not easily deformed into a concave shape when an impact or a vibration is applied to the shadow mask, so that a good image can be displayed. The electron beam passing holes of the shadow mask are each formed of an upper hole etched from the panel side of the shadow mask and a lower hole etched from the electron-gun side of the shadow mask. In each electron beam passing hole located in the peripheral portion of the shadow mask, the ratio of an upper-side etching quantity to a lower-side etching quantity is controlled to be 1.8 or less. By adjusting the balance in strength relative to compressive stresses between the panel side and the electron-gun side of the shadow mask, it is possible to prevent the shadow mask from being deformed into a concave shape.
