| abstract |
An aspect of the present invention resides in a display device that includes a display element including a light source, and a surface film disposed so as to overlap with the display element and including a thermoplastic elastomer composition, the thermoplastic elastomer composition satisfying conditions (1) and (2) below, the surface film satisfying conditions (3) and (4) below: (1) The melt flow rate (ASTM D1238, 230°C, 2.16 kg load; MFR) is not less than 30 g/10 min. (2) The type A hardness (momentary value) measured by a method in accordance with JIS K6253 is 60 to 90. (3) The thickness is not less than 300 µm and not more than 2 mm. (4) The total light transmittance measured by a method in accordance with JIS K7361 is 3 to 60%. The display device of the present invention attains an excellent appearance and a good touch offered by the surface film, and can display clearly visible images during illumination periods. During non-illumination times, the display element is not conspicuous and the surface film can fully exhibit its good appearance (decorative effects). Further, for example, a step may be provided on a display section or an operation section to allow the display section or the operation section to be tactually perceived even in circumstances where the display device does not emit light and the display section or the operation section is invisible. Such a step may be easily formed by, for example, injection molding of the thermoplastic elastomer composition. |
