  • Publication number: 20240342599
    Abstract: A non-limiting game apparatus comprises a processor, and the processor displays a main menu image at the time of starting a game. If a player determines a second mode in the main menu image, and further an episode, a game starting point selection image is displayed. The player selects and determines the starting point of a game part that is selectable from a plurality of game parts constituting a scenario in the game starting point selection image, thereby to start a play of a virtual game. If the game part being played is cleared, a next game part become playable.

  • Patent number: 8059233
    Abstract: There is disclosed a transflective liquid crystal display having pixels each including a reflective region and a transmissive region. The aperture ratio of the pixels can be enhanced. End portions of two adjacent color filters are overlapped to form an optically shielding portion for each pixel. The optically shielding portion and the reflective region cooperate to form an optically shielding film acting as a black matrix for the transmissive region. The aperture ratio is enhanced by improving the positional relationship between the reflective regions and the color filters.
